"Workload Transfer from California Service Center to Texas Service Center
On March 8, 2013, USCIS transferred some casework from the California Service Center to the Texas Service Center to balance overall workload with processing capacity at the centers. The affected casework includes the following forms:
I-821D, Consideration of Deferred Action for Childhood Arrivals
I-765, Application for Employment Authorization (when filed concurrently with the I-821D)
I-765 Worksheet (PDF) (when filed concurrently with the I-821D)
Effect on Customers: As a result of these changes, Deferred Action for Childhood Arrivals (DACA) requestors may receive a letter from USCIS letting them know their request for DACA is now pending at the Texas Service Center instead of the California Service Center. Customers do not need to take any action." - USCIS, Mar. 12, 2013.
