Since April 1st, 2006, USCIS requires all the I-129 forms should be submitted to Vermont Service Center (VSC), while all the I-140 and I-485 forms should be submitted to Nebraska Service Center (NSC). According to this new bi-specialization procedure, pending I-485 applications would be processed by their original service centers.

Recently, USCIS is transferring all pending I-485 applications from CSC to NSC, and from VSC to TSC. This includes cases that are subject to visa retrogression and security/background checks. Transfer notices will be sent and the USCIS online system will be updated when a transfer occurs. USCIS confirmed that transferred cases will go into the queue based on original filing date and not the date of the transfer. If you have a pending case in either CSC or VSC, please keep an eye on this matter.
