H-1B Visa Frequently Asked Questions

What is the purpose of the H-1B visa?

The H-1B visa is designed to allow U.S. employers to hire foreign nationals for temporary employment in specialty occupations that require specialized knowledge or expertise, such as science, technology, engineering, or mathematics (STEM) fields.

What qualifies as a "specialty occupation" for the H-1B visa?

A specialty occupation typically requires at least a bachelor’s degree or its equivalent in a specific field of study. It must also involve the application of specialized knowledge and skills.

How long can I stay in the U.S. on an H-1B visa?

H-1B visa holders are initially granted up to three years of stay, with the possibility of extension for a total of six years. Extensions beyond six years may be possible in certain circumstances, such as if you have a pending employment-based green card application.

Do I need a job offer to apply for an H-1B visa?

Yes, you must have a job offer from a U.S. employer to apply for an H-1B visa. The employer must file an H-1B petition on your behalf.

How does the H-1B visa application process work?

The H-1B application process typically involves the following steps:

An employer files an H-1B petition with the U.S. Citizenship and Immigration Services (USCIS).

USCIS reviews the petition and, if approved, issues an H-1B approval notice.

If you are outside the U.S., you must apply for an H-1B visa at a U.S. embassy or consulate.

If you are already in the U.S., you may need to apply for a change of status.

Is there an annual cap on the number of H-1B visas issued?

Yes, there is an annual numerical cap on the number of new H-1B visas issued each fiscal year. The regular cap is 65,000, and there is an additional 20,000 visas available under the H-1B Master’s Cap for individuals with advanced degrees from U.S. institutions. Some employers, such as universities and certain non-profit organizations, are exempt from the cap.

Can I apply for permanent residency (a green card) while on an H-1B visa?

Yes, it is possible to apply for permanent residency while on an H-1B visa. Many H-1B visa holders pursue employment-based green cards, and the process can be started by their employer.

Can my spouse and children accompany me on an H-1B visa?

Yes, your spouse and unmarried children under 21 can accompany you on an H-4 visa. However, H-4 visa holders are generally not allowed to work in the U.S. unless they qualify for certain exceptions.

Can I change employers while on an H-1B visa?

Yes, you can change employers while on an H-1B visa, but your new employer must file an H-1B petition on your behalf. You can begin working for the new employer as soon as they file the petition.

Can I travel outside the U.S. while on an H-1B visa?

Yes, you can travel outside the U.S. while on an H-1B visa, but you must have a valid H-1B visa stamp in your passport and a valid H-1B approval notice. You should also consult your immigration attorney or employer for guidance on travel.

I've had the pleasure of working with DLG on various petitions over the past few years. US immigration could be quite complex and overwhelming making knowledgeable, trustworthy help critical to successfully navigate through the process. The team at DLG (Dana, Leyla, Jennifer, Melisa) are extremely knowledgeable, thorough, patient, transparent and responsive. Definitely recommend them!!

Appreciate the Davidson Law Group for helping me secure approval for my H1b visa. The paralegal working with me was very responsive in answering the questions I had (usually always responded to my messages the day of my inquiry) and the answers were always detailed and professional. Would recommend working with the law group!

To the entire Davidson Law Group team, thank you so much for all the support during the past three years of my immigration journey in the US. They were especially supportive and responsive to all my queries about the different visas and were always prompt and kind. I especially appreciated it when Leyla got back to me beyond working hours on a Friday with, "Congratulations, your H1B has been picked." It definitely made my and my close ones' weekend a tad better. I would recommend them for sure just because I appreciated their humane approach to all of their cases. Kudos to all of you.
