We've been selected for DV-2017, in August we submitted all paperwork for AOS to USCIS, in October we did fingerprints, then for 3 months nothing was happening and on January 10 we receive notice that our case has been moved from Nebraska to NBC ( our FO is New York), my question is, is it standard procedure that they move case to NBC , should schedule INFOPASS, do you think it's unusual that we wait so long and other peoples average wait time from fingerprints to interview is 30-60 days.
