Your approval will happen -
Many factors come into play when reviewing applications. Here are some assumptions and facts:
USCIS is not reviewing applications on a first come, first served basis
Perhaps, some applications/individuals are easier to approve, due to background screenings, etc
Remember that USCIS is also revewing other cases, in addition to DACA - think of it as having a bunch of piles, and then DACA is added on top of the piles
The increased number of new applicants has decreased the turnover rates of many Service Centers
My assumption is that some Service Centers are experiencing a high level of applications, and therefore are re-routing applications either to other Service Centers or Local USCIS satellite offices (It has happened before - Cal to Nebraska, Vermont to Nebraska, Vermont to Local Office, etc)
(If anyone has any rebuttals to the above statements, please correct me where I was mistaken)
Therefore, wait patiently...I know it is hard, and it is even harder when you know/have heard of someone getting approved 2 months, let alone two weeks, since their biometrics were taken...but it will happen...either you get an RFE, or the approval, but you will eventually hear from them...I hope you get the latter and not the former!
Try to avoid checking your case status every. single. day., and keep your mind busy...it will come as a surprise, but you will be glad it happened...
They received my App on Aug 16, had Bios on Sep 14th, and was approved this past Feb 14th...I was in your same boat...therefore, it will eventually happen...Trust me
