We went for 485 stamping last Friday(02/27). Friday usually low volume day. We reached JFK building (side entrance) at 7am, nearly 150 people standing in front of us. By the time we come to security screening 50 people behind us. Took the token at 7:45am and got I-89 forms. Passport stamping started at 8am, only one guy with French beard doing multiple things including passport stamping. Officer called us at 11:00am took all documents 485 courtesy copy, EAD(s), AP(s), passport, I-89 and 2 photos. No questions asked stamped passport and said cards will come in 6-12months. We got out around 11:15am. Its better to stand in line early.
