To move to a different employer, the new employer files a new I-129 petition, and the worker should not begin the new job until USCIS approves it. The P-3 principal does not file Form I-539 for an extension. First check the worker’s authorized-stay end date on the I-94 and distinguish it from the visa stamp’s expiration date.
First check when the authorized stay ends
Check the worker’s admission record, including the I-94, for the date through which they are authorized to stay. A visa stamp’s expiration date is not the same thing as the end of authorized stay in the United States. The Department of State explains the distinction and warns that staying beyond the authorized period can create immigration and future visa consequences: visa expiration and authorized stay.

Use that date to assess filing timing, but do not assume that a pending petition by itself resolves every status or work-authorization issue. The actual effect depends on the filing and the worker’s circumstances.
Extending P-3 status with the current employer
The current employer or petitioner files Form I-129 to request an extension for the P-3 principal. USCIS’s Form I-129 page and I-129 instructions describe the employer petition and continuation of previously approved employment. The employer is the petitioner because the request concerns the offered work and the terms of the approved employment.
#1 Best Overall
The P-3 principal cannot use Form I-539 to request this extension. USCIS’s Form I-539 materials address other nonimmigrant applications, including certain P-4 dependent filings, but do not make I-539 the extension route for the P-3 principal.
When an extension is pending
A USCIS reference guide describes up to 240 days of continued work for a nonimmigrant employee when an I-129 extension is filed before the prior authorized period expires. That rule is conditioned on continuing with the same employer and remains subject to the original authorization’s conditions and limitations. The guide also says work authorization automatically ends if the extension is denied, even if fewer than 240 days have passed: USCIS employer reference guide.
Do not treat 240 days as blanket permission to work, permission to work for a new employer, or a guarantee that the rule applies to a particular P-3 case. Confirm the filing date, receipt and case circumstances against current USCIS guidance before relying on continued work authorization.
Changing to a different employer
A different employer must file a new Form I-129 petition for the P-3 employment. USCIS’s I-129 instructions identify “Change of employer” as a filing basis for a beneficiary who will begin employment with a new employer in the same nonimmigrant classification. USCIS’s temporary worker guidance says the worker must wait for approval of the new employer’s petition before starting that employment.
A pending extension filed by the current employer does not itself authorize work for the new employer. The petitioning employer, proposed employment and approved terms matter; coordinate the filing and start date with the new petitioner.
When an amended petition may be needed
Not every update to a job is a new-employer case or a routine extension. USCIS’s I-129 instructions distinguish non-material changes from material changes in the terms or conditions of employment, training, or eligibility. A material change may require an amended petition. Compare the proposed change with the actual approved petition and use the current instructions to determine the appropriate filing basis.

An extension or change of status approved by USCIS while the worker is in the United States does not issue a new visa stamp. A person who remains in the country may have authorization to stay under the approved status without obtaining a new visa, but after departure a valid visa may be needed to seek admission again. Check the visa’s validity, admission requirements and the case-specific consequences of travel before leaving. Department of State guidance explains that visa validity and authorized stay are different and addresses travel after a USCIS status decision: visa expiration and authorized stay.

Before the employer files
- Confirm the I-94 authorized-stay end date and the current petition’s validity period.
- Identify whether the case is a continuation with the same employer, a new-employer petition, or a material change requiring an amended petition.
- Use the current Form I-129 edition and instructions. Check USCIS’s form page for current filing information, including fees and where to submit.
- Coordinate the filing and proposed work start date with the petitioner; do not begin work for a new employer before approval.
- Review travel plans separately, including whether the worker will need a valid visa to return after departing the United States.
Government sources do not establish one universal filing address, fee, processing time, evidence package, or outcome for every P-3 case here. Confirm current requirements with USCIS and seek qualified immigration counsel for case-specific questions.
