A visa for individuals with extraordinary ability.

In US immigration processes, your claims must be more likely than not to be true. This means if something appears more true than false, USCIS should accept it as true. To meet this standard, the visa petitioner should provide documents that convincingly support the claim’s validity.

For instance, to prove you received VC funding, you could provide signed SAFE agreements with a VC, a published article about your funding round, and documentation about the relevance of the VC.

Keep in mind that theory and practice do not always perfectly align. It’s crucial you speak to an experienced legal team to avoid spending time and money on documentation that does not support your case.

Yes, you can reapply as many times as you wish.

However, bear in mind that when you submit a green card petition or it’s submitted on your behalf, immigration authorities may sometimes see this as an indication that you plan to live in the US permanently (immigrant intent). This is incompatible with a key requirement for most temporary visas, which must express an intent to relocate to the US temporarily only.

If you plan to, or need to file a temporary visa application after filing an EB-1A application, this may affect your eligibility to renew or obtain your temporary visa.

Rules around resubmissions are nuanced, so it is advisable to consult with an experienced immigration attorney to understand all the implications.

Yes in most cases (when your priority date is current), but we generally advise against it.

Filing for Adjustment of Status signals clear immigrant intent. If your EB-1A is denied, it could make obtaining non–dual intent visas (such as E-1 or E-2) more difficult.

The safer approach: secure EB-1A approval first, then apply for Adjustment of Status.

To qualify for an EB-2 NIW (National Interest Waiver), you must have either an advanced degree (master’s or higher), a bachelor’s degree with at least five years of progressive work experience, or demonstrate exceptional ability in your field.

Exceptional ability means a level of expertise significantly above the ordinary, proven by meeting at least three of six USCIS criteria, such as membership in professional associations, recognition from experts in your field, or a significant impact on your industry.

Additionally, you must show that your work benefits the U.S. in a meaningful way, such as improving the economy, advancing technology, enhancing healthcare, strengthening national security, or addressing other critical needs. USCIS evaluates this based on how important, urgent, and far-reaching your contributions are.

No, one of the main advantages of the EB-2 NIW is that you can self-petition, meaning you do not need a U.S. employer to sponsor you or go through the labor certification (PERM) process, which is typically a lengthy and complex requirement for employer-sponsored Green Cards.

Instead, you must prove that your work is in the national interest of the U.S. and that waiving the job offer requirement would benefit the country.

To prove that your work is in the national interest, you must show that it has a direct and significant impact on the U.S. in areas such as technology, healthcare, education, economic growth, or national security.

Your contributions should provide clear benefits to the country as a whole, beyond just your employer or local community.

You can demonstrate this through government reports, industry publications, media coverage, patents, or letters from experts confirming that your work aligns with national priorities and contributes to broader advancements in society, an industry, or the economy.

A strong EB-2 NIW petition must demonstrate that you have the expertise and experience to advance your endeavor and that your work has substantial merit and national importance.

Evidence may include receiving awards, publishing research, holding patents, and having relevant work experience in your field.

Support from employers, investors, or institutions can further strengthen your case. Additional factors include serving as a judge of others' work, holding memberships in prestigious organizations, and being featured in media coverage.

The more solid and well-documented your evidence, the stronger your petition.

Yes. It’s possible to pursue both strategies simultaneously. However, it’s far more common to apply for the O-1 and then pursue the EB-1A. Many applicants use the O-1 as a “bridge” to work legally in the U.S. while building their profile for the EB-1A. The O-1 is temporary, while the EB-1A leads to permanent residency.

Yes. Evidence of press coverage—especially in reputable, independent outlets—is strong proof of recognition in your field. However, not all articles are born equal, and some are far more relevant than others. The article should be mostly about you and your work, have a listed author, and date.

No. Technically you can self-file (for EB-1A) or have an employer file without an attorney. However, due to the complexity of the evidence, most applicants strongly benefit from legal representation.

They serve to contextualize and validate your achievements. Strong letters from independent experts can significantly strengthen your case. Letters are not going to be the cornerstone of the application, but are very relevant and helpful to the case.

No. Only U.S. citizens can sponsor parents. Once you become a citizen (typically after holding a green card for 5 years, or 3 years if you became permanent resident through marriage with a US citizen), you may petition for them.

Extraordinary ability is the language you must use in O-1 and EB-1A cases, and it means you are among the very top in your field. Exceptional ability (EB-2 NIW wording) means you have expertise significantly above the average but not necessarily at the very top.

Yes, but they are generally weaker than major national or international awards. They can still support your profile when combined with stronger evidence. In most cases regional awards are not useful for the awards criteria but are still helpful to establish recognition in your field.

Yes. Patents that have been commercialized or frequently cited can help demonstrate original contributions. However, simply holding a patent that has not been applied or recognized by others in the field is not sufficient to establish this category.

It depends. For scientists and academics, publications in peer-reviewed journals are often a cornerstone of the case. For professionals in business, arts, or other industries, other types of evidence (press, awards, leadership, impact) may carry more weight.

Absolutely. Speaking engagements—especially at well-known or international conferences—show that you are recognized as an authority in your field. The more selective and prestigious the event, the stronger the evidence. Although it does not fall into a specific category, it is very important for the final merits evaluation.

EB-1A is an immigrant visa that leads directly to a green card and permanent residence, while O-1A is a non-immigrant work visa valid for up to 3 years with extensions available.

EB-1A allows you to self-petition without employer involvement, whereas O-1A requires an employer or agent sponsor. Both require proving extraordinary ability, but EB-1A applies a higher standard of proof.

Generally, yes.

Both visas require proving extraordinary ability using similar criteria, but USCIS applies a more flexible standard for O-1A. Regional recognition and recent accomplishments tend to carry more weight for O-1A, while EB-1A requires sustained national or international acclaim over a longer period.

Many individuals who qualify for O-1A need additional time and achievements before being ready to apply for EB-1A.

Yes, and many people do.

A common strategy is to file for O-1A to enter the U.S. quickly while an EB-1A petition is pending or while you continue building your profile. However, because O-1A is technically a non-immigrant visa, having immigrant intent requires careful planning.

This approach is allowed, but it’s important to understand the legal implications and structure the filings correctly.

Both visas require meeting at least 3 criteria from their respective lists.

• O-1A has 8 criteria.
• EB-1A has 10 criteria (two additional ones apply to performing arts).

Both O-1A and EB-1A petitions can use premium processing for $2,805 ($2,965 since March 2026), which guarantees USCIS action within 15 business days.

Without premium processing, O-1A petitions and EB-1A I-140 petitions are generally processed on similar timelines. The key difference is that EB-1A approval is only the first step toward permanent residence.

After I-140 approval, EB-1A applicants must still complete adjustment of status or consular processing, which adds several additional months to the overall green card timeline.

Yes. Government filing fees for EB-1A petitions are generally comparable to other employment-based immigrant visas.

However, the total cost can vary significantly depending on legal fees, the complexity of the case, and whether optional services—such as premium processing—are used.

In a self-petition, the applicant is responsible for paying the premium processing fee.

While technically the fee can be paid by anyone, this is uncommon in practice and is usually paid directly by the applicant.

Yes.

Attorneys often charge additional fees to prepare responses to Requests for Evidence (RFEs) or Notices of Intent to Deny (NOIDs). This can increase the total legal cost beyond the initial estimate for the EB-1A petition.

USCIS guarantees action on the EB-1A petition within 15 business days when premium processing is used.

If a Request for Evidence (RFE) is issued, the 15-day clock pauses and restarts after USCIS receives your response.

Standard EB-1A processing times vary by USCIS service center and workload.

In many cases, processing can take several months to over a year without premium processing.

For most countries, EB-1A does not have a visa backlog and visas are immediately available.

However, applicants born in India and China typically face multi-year backlogs due to high demand.

After EB-1A approval and once a visa number is available, adjustment of status within the U.S. typically takes 12–18 months.

For applicants using consular processing, timelines often range from 6–12 months, depending on the U.S. consulate.

No. Premium processing only accelerates USCIS’s review of Form I-140.

It does not reduce the time needed to prepare your petition, gather evidence, or complete adjustment of status or consular processing after approval.

No. EB-1A allows self-petitioning.

You do not need a U.S. employer, a job offer, or a labor certification to file an EB-1A petition.

Yes, if you can demonstrate field-level impact.

USCIS focuses on the quality, relevance, and influence of your work rather than the number of years of experience in your field.

USCIS evaluates EB-1A petitions using a two-step process.

First, you must either demonstrate a major internationally recognized award or meet at least three of the ten regulatory criteria. While three is the minimum, satisfying more criteria generally strengthens your case.

Second, USCIS conducts a final merits review, assessing the overall quality, significance, and impact of the evidence compared to others in your field.

NIW stands for National Interest Waiver.

It refers to a waiver of the job offer and labor certification (PERM) requirements that normally apply to EB-2 petitions.

No.

You may qualify with:

• a master’s degree, or
• a bachelor’s degree plus five years of progressive work experience.

Yes.

Many applicants file for an EB-2 NIW while holding a nonimmigrant visa such as H-1B, O-1, or L-1.

In most cases, you can continue to maintain your current lawful status while your petition is pending.

Yes.

Filing both petitions simultaneously is a common strategy.

Each category has different requirements, and approval of one does not depend on the other.

An RFE means the USCIS officer needs more information before making a decision.

You will receive a notice explaining what additional evidence is required.

Responding thoroughly and on time is critical to the success of your petition.

The E-2 doesn't directly lead to a green card, but E-2 holders have several pathways to permanent residence.

Options include the EB-5 immigrant investor program, EB-1A extraordinary ability, EB-2 NIW national interest waiver, or employer-sponsored green cards through the PERM process.

Only two categories allow self-petitioning: EB-1A (Extraordinary Ability) and EB-2 NIW (National Interest Waiver).

For all other categories, your employer must act as the petitioner and file on your behalf.

Both self-petition categories have the added benefit of not requiring a PERM labor certification or a specific job offer.

Standard I-140 processing time is approximately 6 to 12 months or longer, depending on the USCIS service center handling your case and the specific category you filed under.

You can check current estimates on the USCIS processing times page.

Filing with premium processing reduces this to either 15 or 45 business days depending on your category.

The total depends on your employer size.

For a large employer (26+ full-time employees), the base filing fee is $715, the Asylum Program Fee is $600, and the premium processing fee is $2,805 (before March 1, 2026) or $2,965 (on or after March 1, 2026).

That brings the total to $4,120 or $4,280 respectively.

The filing fee and Asylum Program Fee must be submitted as two separate payments.

No. An approved I-140 confirms that you meet the qualifications for your employment-based category, but it does not grant permanent residence.

You still need to file Form I-485 for adjustment of status if you're in the U.S., or complete consular processing if you're abroad once your priority date becomes current.

The I-140 approval establishes your place in line.

No. Form G-28 has no filing fee.

USCIS accepts it at no cost.

Your immigration attorney may charge their own professional fees for representing you, but the form itself is free to submit alongside your visa application, petition, or appeal.

Form G-28 is used for immigration matters before USCIS within the United States.

Form G-28I is a separate form used for matters outside the U.S., and it allows a broader range of representatives to file, including attorneys who are not licensed in the U.S. and certain family members.

If your case is handled domestically by USCIS, your attorney will use the standard G-28.

Yes. USCIS requires a new Form G-28 for each separate application, petition, or appeal.

Even if the same attorney is handling multiple filings for you, they must submit a new G-28 with each one.

The form applies only to the specific case it is filed with and does not carry over to other matters.

Yes. You are always allowed to represent yourself before USCIS.

Form G-28 is only necessary when you want a licensed attorney or accredited representative to act on your behalf.

If you choose to handle your own visa process, USCIS will communicate directly with you.

However, for complex petitions or cases involving RFEs, many foreign nationals find that working with an immigration attorney leads to better outcomes.

The total timeline from I-140 filing to green card issuance is approximately 3 to 5 years for Indian nationals.

That includes petition adjudication (15 business days with premium processing for EB-1A and EB-1B, 45 business days for EB-1C, or 6-12 months with regular processing), the priority date wait of roughly 2 to 3 years, and I-485 processing of 8 to 14 months.

You cannot speed up the visa bulletin itself, since it moves based on overall demand and supply of visa numbers.

You can compress the stages you do control: use premium processing to get your I-140 approved quickly, file your I-485 at the earliest eligible moment, and look at cross-chargeability if your spouse was born in an eligible country.

Yes. The EB-1 India backlog of 2 to 3 years is far shorter than the EB-2 India backlog of 10+ years.

For qualified applicants, the EB-1 is the fastest employment-based path to a green card by a significant margin.

Your approved I-140 priority date is portable. Even if you leave the sponsoring employer, you can keep the priority date and apply it to a future green card petition, whether it's a new EB-1, EB-2, or EB-3 filing.

The I-140 premium processing time is 15 business days for EB-1A, EB-1B, PERM-based EB-2, and EB-3 petitions. EB-1C and EB-2 NIW petitions have a 45-business-day premium window.

If USCIS issues an RFE, the clock resets, and a new period of the same length begins after you respond.

Yes. You can file Form I-907 at any point while your I-140 is pending to upgrade to premium processing.

The premium clock starts when USCIS accepts the I-907, not when the original I-140 was filed.

No. Premium processing only guarantees a faster decision. It doesn't change the adjudication standard or make approval more likely. The same officer at the same USCIS service center reviews your case under the same criteria.

A well-prepared petition is what drives approval rates, not the processing speed.

Form I-140 is the immigrant petition for employment-based green cards. Form I-129 covers nonimmigrant worker visas like H-1B and L-1. Both forms are eligible for premium processing through Form I-907, but they have different fee amounts and processing timeframes.

The I-140 premium processing time discussed in this guide applies only to the green card petition.

Most strong EB-1A petitions include 6-10 letters, with a mix of 3-4 independent expert letters and 2-4 collaborator letters. The exact number matters less than the balance.

Five sharp letters with strong field-wide impact paragraphs beat ten generic ones, and packages made entirely of co-author or supervisor letters often draw an RFE on the independence question.

Both, but the package should lean independent. USCIS gives more weight to letters from writers who never collaborated, employed, or co-authored with the petitioner, because they have nothing to gain from the outcome.

Collaborator letters add useful depth on specific projects and day-to-day scope, but they can't carry the case alone. Aim for at least half of your letters from independent writers.

Usually not without rewriting. O-1A letters establish extraordinary ability for a specific O-1 employment period. EB-1A letters have to show sustained national or international acclaim, which is a higher bar, and they need a clear field-wide impact paragraph that O-1A letters often don't bother with.

Letters can share underlying facts, but the framing and the level of detail in the impact section usually need work before an O-1A letter is EB-1A-ready.

You have a few options. If premium processing isn't already running, you can wait and file once the letter is in. If you're under a hard deadline (priority date, status pressure), you can file with the strongest letters you have and supplement the package with the missing letter through an unsolicited submission before adjudication.

A third option is filing a motion or response if the missing letter triggers an RFE later. Talk to your attorney before letting a deadline drift.

You need to meet at least 3 of the 10 criteria with well-documented evidence. Meeting more than 3 strengthens your petition, but 3 is the minimum.

The quality of your evidence matters as much as the number of criteria you satisfy. A strong petition with 3 well-supported criteria can be more persuasive than a weak case claiming 5. For a detailed look at each criterion, see our EB-1A eligibility criteria guide.

The EB-1A approval rate varies, but well-prepared petitions with strong evidence have a high chance of success. That said, USCIS applies a rigorous two-step review: first checking whether you meet at least 3 criteria, then evaluating the totality of your evidence in a final merits determination.

Working with an experienced immigration attorney can significantly improve your chances. Weak petitions are more likely to receive a Request for Evidence or denial.

Standard EB-1A processing time for the I-140 petition ranges from 4 to 10 months, depending on USCIS service center workload. With premium processing, you'll get an initial response within 15 business days.

The total visa timeline, including petition preparation and adjustment of status or consular processing, is typically 6-18 months from start to green card. For the latest data, see our EB-1A processing time guide.

Yes. The EB-1A is one of the few employment-based green card categories that allows self-petitioning. You file Form I-140 on your own behalf without needing a job offer, employer sponsor, or PERM labor certification.

You just need to show that you intend to continue working in your area of extraordinary ability in the United States.

The EB-1A filing fees include $715 for the I-140 petition, plus an optional premium processing fee of $2,965.

There's also an Asylum Program Fee, which depends on your filing type: $600 for regular petitioners, $0 for nonprofits, and $300 for small employers or self-petitioners.

If you file for Adjustment of Status (I-485), that's an additional $1,440.

Attorney fees vary based on case complexity. For a full breakdown, see our EB-1A cost guide or get a personalized estimate with the pricing tool.

The EB-1A is for individuals with extraordinary ability across sciences, arts, education, business, or athletics, and allows self-petitioning. The EB-1B is specifically for outstanding professors and researchers and requires employer sponsorship.

The EB-1A has 10 criteria (meet 3), while the EB-1B has its own set of requirements focused on academic and research achievements. The EB-1A is generally more flexible because it doesn't require an employer.

Yes. Your spouse and unmarried children under 21 can be included as derivative beneficiaries on your EB-1A petition. They will receive their green cards at the same time as you, either through Adjustment of Status or consular processing.

Once they have green cards, they have full work authorization in the United States.

Yes. USCIS allows concurrent filings because each is a separate I-140 petition with its own receipt number and adjudication. The two filings cost you two sets of filing fees and attorney work, but they give USCIS two independent paths to approve your green card on the same underlying evidence.

Concurrent filing is most useful when you want maximum speed and your evidence portfolio plausibly supports both standards.

Indirectly. An approved EB-2 NIW doesn't automatically count as EB-1A evidence, since the standards are different. But the NIW approval gives you a documented USCIS endorsement of your endeavor's substantial merit, and you can keep your earlier NIW priority date if your later EB-1A is approved.

Many applicants use an approved NIW as a foundation while they build the additional acclaim evidence needed for EB-1A.

You don't switch a pending I-140 from one category to another, since each filing locks in its own category. You can file a new EB-1A petition while your EB-2 NIW is still pending, and you can retain your earlier priority date through the EB-1A I-140 if the NIW was approved before being superseded.

Talk to an attorney before filing the second petition so the priority-date portability mechanics work as expected.

Both categories are technically self-filable, but the evidence pack makes or breaks the case in either one. Most successful petitions are built with an experienced immigration attorney who can shape the evidence around the right criteria or Dhanasar prong, manage the expert-letter process, and respond to an RFE if one is issued.

The cost of a strong filing usually pays for itself in approval probability, particularly on EB-1A where the final merits determination is heavily judgment-based. Our do I need an immigration lawyer guide walks through when DIY makes sense and when it doesn't.

Yes. USCIS evaluates your endeavor and track record rather than your enrollment status. You don't need the doctorate conferred to qualify for EB-2: a master's degree already meets the advanced-degree route, as does a bachelor's degree plus five years of progressive post-degree experience.

If neither applies, the exceptional-ability route is an alternative, where you show at least three of seven regulatory factors instead of a qualifying degree. The deciding factor is whether your published, cited work supports the Dhanasar prongs.

There's no citation threshold for an NIW, because USCIS doesn't set a number. Citations are persuasive evidence for the second prong since they show others independently build on your work, but they're weighed alongside your publications, grants, recognition, and letters.

A modest record can still be strong against field norms and paired with first-author work.

USCIS doesn't publish an NIW acceptance rate broken out for PhDs, so treat any single figure you see with caution. A doctorate does clear the underlying EB-2 advanced-degree requirement cleanly, which removes one common failure point.

Approval still turns on how well the petition argues the three Dhanasar prongs, especially national importance and the endeavor statement.

No. The EB-2 NIW waives both the job offer and the PERM labor certification the standard EB-2 path requires, which is what makes it a self-petition: you file Form I-140 on your own behalf with no employer sponsor.

You do need to show you intend to keep working in your field in the United States, whether through research, a startup, consulting, or a faculty role.

The EB-2 NIW wait for Indian nationals is among the longest in the system, often running several years, because green cards are capped by country of birth and demand from India is high. An approved petition establishes your eligibility and locks in your priority date, but you then wait for the Visa Bulletin cut-off to reach that date before the final green card step.

Filing earlier secures an earlier place in line, and many applicants hold a temporary status meanwhile.

Yes. Scholarly articles are only one of the 10 EB-1A criteria, and you need to meet at least three. An engineer can build a strong case on original contributions, a critical role, high remuneration, and judging without ever publishing a paper.

Open source can support several criteria. A widely adopted project with real download and dependency metrics is evidence of original contributions, and serving as a maintainer who reviews outside contributors' code supports the judging criterion.

Document adoption with dated, third-party data rather than self-reported claims.

A FAANG-level package, counting base, bonus, and equity, often clears the high remuneration criterion, but the company name alone does not prove it.

The petition has to benchmark your total compensation against credible third-party data for your role and location to show you sit in the top tier.

The petition can be decided in 15 business days with premium processing on Form I-140, or in the standard USCIS queue without it.

After approval, the timeline to the green card depends on your country of birth: EB-1 is generally current or close to current for most countries in 2026, while India and China face additional backlogs at the priority-date stage.

It depends on your evidence and timeline. If you can document four or five EB-1A criteria with strong metrics and letters, filing the EB-1A directly makes sense since it leads straight to a green card.

If you want to be in the U.S. sooner or your record needs another year to mature, the O-1A is a common bridge toward the EB-1A.

U.S. immigration groups employment-based green cards into five preference categories, EB-1 through EB-5, though most professional hiring runs through EB-1, EB-2, and EB-3. On the temporary side, the main employment-based visa types include the H-1B, L-1A, O-1, TN, and E-2.

So the practical answer is a handful of temporary categories plus three or four green card categories that cover the vast majority of cases.

Dual intent means you can hold a temporary visa and pursue a green card at the same time without raising questions about your intent to leave. The H-1B and L-1A clearly allow dual intent, which is why they're popular starting points for a longer plan.

The O-1 is treated flexibly in practice, while the TN and E-2 are tied more closely to temporary stay, so a green card plan on those needs careful documentation.

Among green cards, the EB-1A (extraordinary ability) and EB-2 NIW (national interest waiver) allow self-petition, so the individual files without an employer or a PERM labor certification. The E-2 doesn't use a traditional employer either, since it's based on the applicant's own investment.

Every other major work visa, including the H-1B, L-1A, O-1, TN, and the standard EB-2 and EB-3 green cards, requires an employer or a job offer.

The immigrant categories, EB-1A, EB-1C, EB-2 NIW, and EB-2 or EB-3 through PERM, lead directly to a green card. The temporary work visas don't grant permanent residence on their own, but several act as bridges.

An H-1B holder can move through PERM to EB-2 or EB-3, an L-1A manager to the EB-1C, and an O-1A performer to the EB-1A.

For eligible candidates, the visas without a lottery or labor certification tend to move fastest. The O-1 and L-1A have no annual cap, so a qualified case can be filed at any time, and the TN can sometimes be obtained at the border for Canadian citizens within days.

Speed also depends on whether premium processing is used, which guarantees USCIS action within 15 business days for an added fee, so the right answer depends on the candidate's profile and how urgently you need them.

No. The EB-1A priority date is not current for India because EB-1 for India is oversubscribed and its final action date in the Visa Bulletin is retrogressed. A visa number is only available once your priority date falls before the EB-1 India cut-off in the current bulletin.

Check our Visa Bulletin reading guide to confirm where the date sits this month.

No one can give you a reliable specific date, and you should be wary of sources that do. The EB-1 India final action date moves based on the backlog ahead of you, the annual supply of visa numbers, India's per-country share, and how the Department of State paces the category through the year.

The practical approach is to read the Visa Bulletin each month and track whether the EB-1 India date is advancing, holding, or retrogressing.

Yes. EB-1A is a self-petition, so you can file Form I-140 from India without an employer, a job offer, or PERM labor certification. Filing sets your priority date and locks your place in the EB-1 India line.

Because of the backlog, you'll typically wait for your priority date to become current before finishing through consular processing abroad or adjustment of status if you're in the U.S.

Often, but not always. EB-1 generally carries a final action date ahead of EB-2 and EB-3 for India because it's the highest-preference category with its own per-country allotment, so a successful EB-1A move can put you in a shorter line.

It's only faster if you genuinely qualify for extraordinary ability and if EB-1 is meaningfully ahead of your current category, so the realistic answer depends on your record and your existing priority date.

Generally yes. When you file a new EB-1A petition, you can usually recapture the priority date from an earlier approved I-140, so the date from your EB-2 or EB-3 case carries over to your EB-1A case. That can preserve months or years of waiting rather than starting the line over.

Because the rules around which prior petitions qualify can get specific, confirm your situation with an immigration attorney before you rely on the earlier date.

Yes, if you already meet an EB-2 basis at the time you file Form I-140. Because your doctorate isn't conferred yet, the petition can't rely on the PhD itself, so it has to stand on a conferred master's, a bachelor's plus five years of progressive experience, or exceptional ability.

Once one of those is in place, you can self-petition mid-program and lock in a priority date.

It depends on whether you have a qualifying EB-2 basis now and how backlogged your country is. If you have a solid basis and face a long EB-2 line, filing during the program secures an earlier priority date while your record keeps growing.

If your case leans mostly on the PhD or your evidence is still thin, waiting until conferral can produce a stronger petition.

Yes. A STEM PhD on F-1 can typically work on OPT and the 24-month STEM OPT extension while the NIW I-140 is pending, and you can pursue H-1B at the same time.

The NIW is a separate filing, so it runs in parallel with your work authorization rather than replacing it.

Filing Form I-140 establishes your priority date, which is your spot in the queue for permanent residence. Because every country currently faces an EB-2 backlog, an earlier priority date means more time accruing while you wait, which is a core reason candidates from India and China often file as soon as they have a valid basis.

Check the current Visa Bulletin for cut-off dates.
