i'm a baltimore victim, had interview in last oct., but still nothing. long story short -- it took 2 months to schedule for interview after the transfer, but that's in last aug/sep period when batches of cases were transferred. after that, it looks like fewer cases were tranferred and it took longer (yes, longer than 2 months) to schedule. my problem was my doctor forgot to sign one form, although i sent the form back one day later, for some reason, the case was "frozen" on the shelf for another 5 months until they sent it to fbi for name check, now the check has been taken for 4+ months, still "pending". i called bcis for 5 times (no use, don't do it if your case is at local) and visitied local for 3 times and asked my lawyer to send in request 2 times, all same result, "name check has not been done, once it's done, it will be approved ......."
all i can tell you is the processing speed at local offices is totally UNPREDICTABLE and you have no way to find updates. Service center at least has a better communication.
the interview at baltimore was simple, you don't need to have a lawyer to be with you. BUT, here's my suggestions:
1) bring as many documents as you can think of, besides the ones they ask for. (for your case, some extra docs to prove your marriage). it's not likely they'll ask for them, but if they do and you don't have them in hand, it could cause your troubles/delays;
2) questions are simple, some are related to your wife's visa status since entered u.s., criminal records, your marriage, etc., don't worry.
3) REMEMBER the officer's name in case something happens, you can find the name on his/her door (this is my lawyer's advice).
4) the. whole process (not include waiting time) takes less than 30 mins.
5) the biggest problem is FBI NAME CHECK, if it's already done smoothly, then everything will be fine, otherwise you'll NEVER know WHEN they'll look at your case again, and by that time, some new policies/regulations/whatever may come out, and, believe me, things will only get WORSE.
all in all, it all depends on your luck and i wsih you have a better one than mine.
