USCIS Workload Transfer Updates

USCIS often issues transfer notices to applicants who have a case pending with the Service. The reason for this is to speed up processing. For example, an applicant for work authorization may receive a transfer notice 45 days after her application is pending. In the case of work authorization, the Service is obligated to regulation to adjudicate the application within 90 days, so the transfer notice is to ensure that the regulation is followed. The Service has multiple service centers. While some have specialized functions (Texas and Nebraska adjudicate employment-based immigration petitions; Vermont handles U visas and VAWA cases; Vermont and California handle H-1B visas), many of their duties are shared. Petitions for Alien Relatives and Employment Authorization applications are often transferred.
