Yes, under the H-1B portability provision, a worker may change employers once the new employer files a valid H-1B petition.

Changing employers on H-1B is legal with proper petition filing and compliance with USCIS guidelines.

Changing employers on an H-1B visa is lawful and relatively common, but it must be handled with attention to detail and timing. Your new employer must submit a complete and timely H-1B petition, and your role must continue to qualify as a specialty occupation. It is also essential that you were not out of status at the time of filing, as this can disqualify you from portability. If USCIS later denies the transfer petition, and you have already left your previous job, you may be considered out of status.
