How long does it usually take to go through the whole process in Queens office including wait time?
**updating with interview experience**
went to the new USCIS office on Jackson Ave, LIC (they split the Garden City into Holtsville and LIC). got there about an hour before my scheduled time and waited for about an hour so i had my interview at, pretty much, the actual time on the letter.
So here are the details:
walked in, went through security. be smart and don't carry anything that they will confiscate. they took away a lady's dolphin charm because it had a 'sharp' edge. they also reprimanded a guy for bringing in lollipops but didn't say anything to me about my protein bar.
went to the lady straight ahead, letter stamped then turned right, went to elevator and took it to second floor. a guy also walked into elevator with me and we both handed our letters to the security guard that stood right by the elevator.
i think she put his letter on top of mine because he got called before me (by same officer)
.....it felt good to be prepared.
its almost over. can't wait.
