H-1B Transfer: When Can You Start With the New Employer?

For most workers already in H-1B status, USCIS says "you may begin working for the new employer as soon as they properly file a non-frivolous Form I-129 petition on your behalf, or as of the requested start date on that petition, whichever is later." This is called H-1B portability. It means the new employer does not have to wait for USCIS to approve the new petition before the worker starts, but the new employer must file the petition before the worker's current period of authorized stay ends. The details matter, so this article walks through the conditions and what the rules say when USCIS decides the petition. An H-1B "transfer" is the everyday word for a change of employer.

What USCIS says portability requires

The USCIS H-1B page (reviewed 09/21/2026) makes these points in its section on changing employers:

• The worker may begin working for the new employer once it properly files a non-frivolous Form I-129, or as of the requested start date on that petition, whichever is later.
• "To be eligible for portability, you must not have been employed without authorization from the time of your last admission into the United States, and your new employer must properly file a new, non-frivolous petition before your H-1B period of authorized stay expires."
• The same page covers a current employer too: if your current H-1B employer properly files a non-frivolous Form I-129 requesting new employment or a change of employment on your behalf, you are authorized to work according to the terms of the new or changed employment once that petition is filed, or as of the requested start date, whichever is later.

Conditions in the regulation

The regulation, 8 CFR 214.2(h)(2)(i)(H), says an eligible H-1B nonimmigrant is authorized to start concurrent or new employment under section 214(n) of the Immigration and Nationality Act "upon the filing ... of a nonfrivolous H-1B petition on behalf of such alien, or as of the requested start date, whichever is later." It lists three conditions for being "eligible":

1. The person has been lawfully admitted into the United States in, or otherwise provided, H-1B nonimmigrant status.
2. A nonfrivolous H-1B petition for new employment has been filed on the person's behalf, including a petition for new employment with the same employer, with a request to amend or extend the stay, before the person's authorized period of stay expires.
3. The person has not been employed without authorization in the United States from the time of last admission through the filing of the petition for new employment.

If you are not sure whether you meet the third condition, a licensed immigration attorney is the right person to ask. This article cannot tell you whether it applies to your history.

What happens when USCIS decides the new petition

The regulation says that employment under portability "automatically ceases upon the adjudication of the H-1B petition." "Adjudication" means USCIS's decision on the petition. USCIS's H-1B page describes the same idea in plain terms:

• "If you are eligible for H-1B portability, your employment is authorized until USCIS has made a decision on the Form I-129."
• If the new petition is approved, USCIS says you may continue working for the new employer for the period of time indicated on the new petition approval.
• If the new petition is denied, USCIS says you may continue working for your previous employer if your prior period of authorized employment is still valid, "but your authorization to work based on portability ceases upon denial of the petition."

A related regulation paragraph addresses a series of portability moves. It says that a request to amend the petition or for an extension of stay in a successive portability petition cannot be approved if an earlier request in the chain was denied, unless the previously approved H-1B status remains valid. It also says that denial of a successive portability petition does not affect the ability of the H-1B beneficiary to continue or resume working under a previously approved petition that remains valid, provided status was maintained and there was no unauthorized employment. Because these provisions are technical and depend on the whole job history, discuss them with an attorney before relying on them.

Moving from a cap-exempt to a cap-subject employer

USCIS's H-1B page says that if you are moving from cap-exempt to cap-subject employment, the new employer's H-1B petition will be subject to the H-1B cap, and that a cap-subject employer must first submit an electronic registration. Our guide on what happens after an H-1B registration is selected explains that process. The page also has a separate answer for a worker who stays in a cap-exempt position and takes a concurrent cap-subject job. Read it on the USCIS page rather than relying on a summary here.

Fees, processing and recent developments

We do not list fee amounts here. USCIS publishes them on its fee schedule, and the Form I-129 page shows the current edition of the form and the current fees. For typical timing, use our Form I-129 processing times page or the official USCIS processing times tool.

USCIS's H-1B page also describes an additional payment requirement that applies to certain H-1B petitions, and court orders about it. That requirement has changed more than once, so this article does not summarize it. Whether it applies to a particular petition is a question for the employer and its attorney. Read the USCIS H-1B page for the current state.

Common questions

Do I have to wait for approval before starting?

If you meet the portability conditions, USCIS says you may begin working for the new employer as soon as it properly files a non-frivolous Form I-129 petition, or as of the requested start date, whichever is later.

Who has to file the new petition?

The new employer. USCIS says the new employer "must properly file a new, non-frivolous petition before your H-1B period of authorized stay expires."

Can my current employer's approval carry over?

Not on its own. The regulation requires a nonfrivolous H-1B petition for new employment to be filed on your behalf; portability does not skip the new petition.

Is a second job at the same time covered?

The regulation says an eligible H-1B nonimmigrant is authorized to start "concurrent or new employment" under section 214(n), subject to the same conditions.

What if the new petition is denied?

USCIS says your authorization to work based on portability ceases upon denial of the petition, and that you may continue working for your previous employer if your prior period of authorized employment is still valid. Ask an attorney how that applies to your dates.
