Passport Stamping Exp.
Back again as promised.
Gist of the matter is that my approval notice had specified Baltimore, MD as the center and I had gone to San Francisco, CA center on Friday 16th Aug.
Had a few problems intially - there were two queue's - an appointment queue and a general queue. Wasn't allowed to go via the appointment queue (there was none!) as the guard stopped saying that if the center listed was SFO then I could, so he guided me to the general queue - huge queue, just to get inside the center!
Anyways, after a few "false" starts was finally was able to figure out the room to get to and each place I was told that they might not be able to process the case since it's an out of state center and the file may not be there, etc, etc. Finally submitted my papers - approval notice + Passport at around 1ish (the center closes at 3p!) and around 1:45p names were being called out, fingerprints & signature's taken and the stamped passport (looks pretty ordinary!) given.
It was a long day reaching at 9 in the morning and finally getting out at 2ish but that was more due to mis-information about where one needs to go and confused receptionist's.
If someone needs more information, I can provide more specific details.
Hope this helps!
