SVSS - we learned from what happened in service centers when TPS extension was extended. Here are samples from VSC and TSC:
VSC - January 2003:
-----------------------------------------------------------------------------------
A recent effort to meet TPS deadlines has resulted in reassigning of resources to this caseload. Resources were pulled from most all form types, resulting in additional delays for many of the applications/petitions. The center expects to complete the TPS applications by the end of January.
-----------------------------------------------------------------------------------
TSC - March 2003:
-----------------------------------------------------------------------------------
Temporary Protective Service (TPS) Project
There is a deadline on I-765 El Salvador TPS cases. These cases must be completed by March 9, 2003. The two-month window receipts for these cases were enormous. To meet the timeline it was necessary to shift resources to this effort. This is only a temporary measure that will slightly affect productivity.
Cases past the processing due dates, and cases for which principals have been approved but family members are awaiting action, will be processed immediately upon termination of the TPS project. Age-out cases continue to be processed.
-----------------------------------------------------------------------------------
The problem with TPS is it receives a higher mandate from congress, thus higher priority to meet the deadline, unlike other cases like I-485 or N-400.
