H1B visa workers may be employed by more than 1 employer concurrently. A typical scenario is 1 full time employer and 1 part time employer.
If the H1B visa worker will continue to work for their employer while commencing new employment for a second employer, the second employer must file an H1B visa petition requesting extension of H1B visa status of the worker.
The worker must wait for approval of the 2nd concurrent H1B visa petition before commencing work.
The 2nd concurrent H1B visa petition position must still be a specialty occupation requiring a relevant bachelor ’s degree or foreign equivalent.
