Hello Optimista
Edit: Added third and probably the most important reason SRC vs NSC service center. I was wrong on the service center differences. Texas i.e. SRC is stuck in anti immigrant lane it seems. Just check the 485 processing times.
There are three possibilities:
1) Your case is stuck at SRC. So no action. Just wait and don't worry.
2) If not #1 then it is possible there is some issue with your case. Wonder if you belonged to indian armed forces or something like that. How about your employer being very small one? Think about similar things and if none of them apply then go to #3
3) Pure luck (or lack thereof). The USCIS is moving dates way ahead and it necessarily results in them randomly approving cases much later than yours and somehow some cases slip through their fingers.
I think the best you can do is simply wait (perhaps do an FOIA). If there are no RFEs that's a good thing. Keep your spirits high. I think it will happen. The USCIS is not exactly an empathetic organization. So just keep waiting. Cheers!
p.s. - We all go through the same. It is exceptional for EB-India 485 cases to be rejected. Although overall rejection rate is 7-8% I personally know of no EB-India case being denied.
