Types of U.S. work visas for immigrants - a guide to employment-based visas

The types of U.S. work visas for immigrants fall into two big groups: temporary work visas that let someone work for a fixed period, and employment-based green cards that lead to permanent residence. If you're an immigration specialist building out a global team, that single distinction is the most useful map you can carry, since it shapes everything from sponsorship duties to how long a hire can stay.

This guide profiles each visa briefly (who it fits, the key requirement, and whether it's temporary or permanent), then points you to the detailed guide for the path you're weighing.

How U.S. work visas are organized

Every U.S. work visa answers two questions: how long can the person stay, and who has to file the paperwork. Those two axes explain most of the choices an immigration specialist makes, so it helps to understand them first.

Nonimmigrant (temporary) vs immigrant (green card)

A nonimmigrant visa gives temporary work authorization, while an immigrant visa leads to a green card and permanent residence. The H-1B, L-1A, O-1, TN, and E-2 are all nonimmigrant work visas: the worker can stay for a defined period, then has to extend, change status, or leave. The employment-based green card categories, grouped as EB-1 through EB-3, are immigrant visas that grant lawful permanent residence with no expiration date.

The practical difference shows up in planning. A temporary visa buys you time and flexibility, since you can bring someone on quickly and decide later whether to invest in a green card, while an immigrant visa is a longer process that removes the renewal clock and keeps a valued employee in place for good. USCIS groups work options along this same temporary-versus-permanent split, and many careers run through both: a worker enters on a temporary visa, then moves to a green card category once they qualify.

One concept ties the two together: dual intent. The H-1B and L-1A let the holder pursue a green card while in temporary status without raising questions about intent, while the TN and E-2 are tied more closely to temporary stay, so a green card plan on those needs careful handling.

Sponsor-required vs self-petition

Most U.S. work visas need an employer to act as the petitioner, meaning the company files the case and takes on certain legal duties. The H-1B, L-1A, O-1, and EB-1C all require a sponsoring employer, the TN requires a U.S. job offer, and the E-2 requires the applicant's own qualifying investment rather than a traditional employer.

Two green card categories stand apart because they allow self-petition: the EB-1A (extraordinary ability) and the EB-2 NIW (national interest waiver). A self-petitioner files on their own behalf with no employer and no labor certification, which is why these paths appeal to founders, researchers, and independent professionals. Knowing which category needs a sponsor tells you immediately whether the case lands on your company's desk or the candidate's.

The table below sums up the main categories along both axes.

Temporary work visas (nonimmigrant) and who each fits

Temporary work visas are the workhorses of corporate immigration, since they let a company bring someone on board within a hiring cycle rather than a multi-year green card timeline. Each one targets a different kind of hire.

H-1B: specialty occupation

The H-1B is the default work visa for degreed professionals in a specialty occupation, meaning a role that normally requires at least a bachelor's degree in a specific field, such as software engineers, financial analysts, and research scientists. The catch is that the H-1B is cap-subject: USCIS receives far more registrations than the annual limit allows, so most candidates first have to clear a lottery before the employer can file the full petition.

Before filing, the employer also files a Labor Condition Application (LCA) with the Department of Labor, a wage attestation confirming the company will pay the required prevailing wage. The H-1B allows dual intent, so it works well as a starting point that later bridges to an employment-based green card. For the full picture on the lottery and timelines, see the H-1B visa guide.

L-1A: intracompany transfer

The L-1A moves a manager or executive from a company's foreign office to a U.S. office, which makes it the go-to category when you're relocating existing leadership rather than hiring from the open market. The defining requirement is one qualifying year of employment abroad with the company, in a managerial or executive role, within the three years before the transfer.

Unlike the H-1B, the L-1A has no annual cap and no lottery, so timing is far more predictable. It allows dual intent and pairs naturally with the EB-1C green card for the same managers. The L-1A visa guide covers the qualifying relationship between entities and the seven-year limit.

O-1A and O-1B: extraordinary ability

The O-1 visa is for people at the top of their field, split into the O-1A for sciences, business, education, and athletics, and the O-1B for the arts and entertainment. There's no cap and no lottery, so a qualified candidate can be filed at any time, which makes it a strong option when the H-1B lottery doesn't go your way.

To qualify, the candidate meets at least three of eight USCIS criteria, such as awards, published material about them, or a critical role at a distinguished organization. The O-1 needs a U.S. employer or an agent as petitioner, so it isn't self-petitioned. You can compare it with the H-1B in our O-1 vs H-1B comparison, and the full requirements live in the O-1A visa guide and the O-1B visa guide.

TN: USMCA professionals

The TN visa is reserved for citizens of Canada and Mexico under the USMCA trade agreement, and it covers a specific list of professions, including engineers, accountants, scientists, and management consultants. The hire must have a U.S. job offer in one of the listed professions and the credentials that profession requires.

What makes the TN appealing is speed and renewability: Canadian citizens can often apply at the border, and the status renews in three-year increments with no hard cap. The trade-off is that the TN is not a dual-intent visa, so pursuing a green card while in TN status calls for careful planning to avoid questions about intent.

E-2: treaty investor

The E-2 visa fits an investor or key employee from a treaty country who is putting substantial capital into a U.S. business they'll direct or develop. There's no fixed legal minimum, though consulates expect an amount proportional to the business, and the enterprise has to be more than marginal, meaning it can generate income beyond a basic living for the investor's family.

The E-2 renews indefinitely as long as the business stays active and viable, which gives founders a long runway. It doesn't lead directly to a green card, so a permanent path needs a separate strategy. The E-2 visa guide explains the investment and treaty-country requirements.

Employment-based green cards (immigrant) and how they differ

Employment-based green cards give permanent residence, so they're the right tool when you want to keep a hire for the long term rather than renew a temporary visa every few years. The categories differ mainly on one question: does the worker need an employer and a labor certification, or can they self-petition?

EB-1A: extraordinary ability (self-petition)

The EB-1A is a first-preference green card for individuals with extraordinary ability who can show sustained national or international acclaim. Its biggest draw is independence: there's no job offer required and no PERM labor certification, so the worker self-petitions without any employer involvement.

For HR teams, that independence lifts the company out of the sponsorship role, though the evidentiary bar is high and USCIS scrutinizes these cases closely. The EB-1A visa guide breaks down the ten criteria, and if you're weighing it against the temporary O-1A, our EB-1A vs O-1A comparison maps the trade-offs.

EB-1C: multinational manager or executive

The EB-1C is the green card counterpart to the L-1A, built for multinational managers and executives the company wants to keep permanently. It's employer-sponsored, so the U.S. company files the petition, and it requires a qualifying year abroad in a managerial or executive capacity, much like the L-1A.

Because the criteria overlap so closely, many employers bring a leader in on the L-1A first, then file the EB-1C once the U.S. role is established. Like the EB-1A, the EB-1C is a first-preference category that skips PERM, which keeps the timeline shorter than the standard green card path.

EB-2 NIW: national interest waiver (self-petition)

The EB-2 NIW lets a professional with an advanced degree or exceptional ability self-petition by showing their work serves the national interest of the United States. The "waiver" refers to waiving the usual job offer and PERM requirement, so like the EB-1A, no employer sponsorship is needed.

USCIS evaluates NIW cases under a framework called Matter of Dhanasar, a 2016 precedent decision that weighs whether the work has national importance and whether waiving the standard requirements benefits the country. The NIW suits researchers, founders, and specialists whose work has clear public value. You can see the application steps in our guide on how to apply for an EB-2 NIW.

EB-2 and EB-3 via PERM

For most degreed and skilled-worker hires who don't qualify for a self-petition or a first-preference category, the green card runs through PERM. PERM, short for Program Electronic Review Management, is a labor certification in which the employer proves it tested the U.S. labor market, found no qualified U.S. worker, and will pay the prevailing wage.

The split between EB-2 and EB-3 comes down to the job's requirements: EB-2 covers positions needing an advanced degree or its equivalent, while EB-3 covers professional and skilled roles. Once PERM is certified, the employer files Form I-140 (the immigrant petition for a worker), and the case moves toward a green card. Our PERM EB-2 or EB-3 guide covers how to decide.

How HR and immigration specialists choose the right work visa for a hire

Choosing among the types of U.S. work visas comes down to matching the candidate's profile, how fast you need them working, and whether you want a temporary fix or a permanent hire. Start with the candidate, since their nationality, role, and track record rule most categories in or out before cost or timing enter the conversation.

Quick decision cues by candidate profile

The fastest way to narrow the field is to read the candidate's situation against a few simple cues. A degreed hire from the open market points to the H-1B, with the O-1 as a backup if they have a strong record and the lottery doesn't work out. An existing manager or executive abroad fits the L-1A, paired with the EB-1C green card later, while a top performer with a documented record suits the O-1A or O-1B now and an EB-1A down the line. A Canadian or Mexican professional may take the quick TN route, and an investor or founder from a treaty country fits the E-2.

Cost varies widely by category and who files. For a full breakdown of filing fees and attorney costs, see our guide to U.S. work visa costs.

Where temporary work visas bridge to a green card

Most green card holders started on a temporary visa, so the smart move is to treat the two as one connected plan. A worker on an H-1B or L-1A, both dual-intent visas, can pursue a green card without jeopardizing their status, which is why those are such common starting points.

The bridges follow predictable patterns: an L-1A manager moves to the EB-1C, an O-1A performer builds toward the EB-1A, and an H-1B professional often goes through PERM into EB-2 or EB-3. When you hire on a temporary visa, ask early which green card category the role could lead to, so you can document the right evidence from day one. Comparing two work visas side by side, like our L-1A vs H-1B comparison, often makes the bridge clearer than either visa alone.
