Answer: Yes. Under certain circumstances, an H-1B alien may still be able to port to another H-1B employer even after the alien’s I-94 or last approved petition has expired. In order to port, however, such alien must meet all the requirements of INA § 214(n), including the requirement that the new petition be filed while the alien is in a “period of stay authorized by the Attorney General.” USCIS has previously determined and issued guidance explaining what constitutes a “period of stay authorized by the Attorney General.” One example would be:
Alien is in H-1B status. Employer A timely files a non-frivolous extension of the alien’s H-1B status. Alien’s original petition, approved for Employer A, expires during the pendency of the extension. Alien is then in a “period of stay as authorized by the Attorney General” while Employer A’s extension is pending. Employer B then files new petition and alien wants to port to Employer B. Under INA § 214(n), the alien should be permitted to port because he or she is in a “period of stay as authorized by the Attorney General.”
In other words, porting under INA §214 does not require that the alien currently be in H-1B status as long as he or she is in a “period of stay authorized by the Attorney General.”
