Many people are asking why the White House is estimating six months before DAPA cases (the parent deferred action applications) will be accepted. After all, the DACA program for 2012 is a template and it should be fairly straightforward to design the new program.
But what many are not appreciating is that USCIS adjudicates about four million applications per year for every type of application it works across the entire agency. DAPA and the expanded DACA will add millions of new applications to the workload.
DACA required 900 new employees and DAPA is expected to be six to eight times larger. USCIS will need to ramp up in a way it has never been asked for this new program.
Hopefully, USCIS will pass this test.
