we just did both in NYC, you should have no problem, schedule your appointment before hand, once it's within the 14 day window, there were plenty of appointments when we booked last minute.
At our location they don't take photos, you have to bring them, so I think you need to check the details for the specific location, and they took the 2 photos we had, I'm guessing because we also got a passport card.
The social security office was the worst part of the whole experience.
Then they also combined the first and middle name and they told us they'd need the certificate of naturalization in order to fix it, so we had to go home to get it and come back.
From all the posts I've seen online of various locations, I've never seen a first not being allowed.
O I should have mentioned, guests had to wait in the waiting room. I think the court room ones, outside sit in the back and can observe
Picking it up today, very easy process.
Yes guests are allowed.
Ours was in the office where the interview was and was quick.
Didn't even give a flag or pamphlet.
Others have it in a court room and a judge gives a speech.
Can't really complain for how quick we got the appointment.
Do you happen to be traveling across the border? Because you'll have to wait till you get a passport as well one you take the oath. Maybe there's an agency near you that has same day service.
