Glossary · USCIS forms
I-539 (Change/Extend Nonimmigrant Status)
The form you file to change from H-1B to H-4, F-1, B-2, or to extend nonimmigrant status without leaving the US.
Filed by the worker (not the employer). $470 paper / $420 online + $85 biometrics per applicant. Premium processing available for I-539 H-4 ($2,075). Critical: USCIS counts the date they RECEIVE the filing, not the postmark — use FedEx/UPS overnight or file online; never USPS during the final week of grace period. A denial inside the grace period can trigger an NTA (USCIS resumed this in February 2025).
