Find quick answers to frequent visa questions from our legal experts
Can I reapply for an I-485 after a denial?
Yes, in most cases. You need a valid underlying petition, a current priority date, and a plan to address whatever caused the denial. If the denial was based on an ineligibility finding that still applies, re-filing without a change in circumstances will likely lead to another denial.
If the issue was evidence-based, a new filing with the right documentation can succeed.
How long does an H-1B visa transfer take?
The H-1B visa transfer timeline varies based on the processing track. Regular processing takes roughly three to six months, while premium processing guarantees USCIS action within 15 business days.
Under AC21 portability, you can begin working for the new employer once the petition is filed and you have the receipt notice, so you don't necessarily have to wait for full approval to start your new role.
What's the difference between O-1A and O-1B for content creators?
The O-1A covers extraordinary ability in business, science, education, or athletics, while the O-1B covers extraordinary achievement in the arts.
If your content creation is primarily creative, such as video production, photography, or music, the O-1B is likely the right fit. If you've built a business around content creation, like launching a product line, running an agency, or scaling a media company, the O-1A may be stronger.
The classification depends on the nature of the work you'll perform in the U.S.
Can I get an O-1A visa without a PhD in data science?
Yes. The O-1A has no degree requirement. While most data scientists who pursue this visa hold a master's or PhD, which strengthens the petition, USCIS evaluates you on the 8 criteria, not on your degree.
A data scientist with a master's degree, strong publications, meaningful open-source contributions, and high compensation can build a winning case without a doctorate.
