I went through security and was directed by the lady at the front desk to sit in the waiting room if I was there for the Oath Ceremony and told to have my green card ready. I was about 30 minutes early (my appt was for 1:30).
My appointment was scheduled at 7:15 am. Yes, 7:15 in the morning. I arrived the USCIS office on W. Badura Ave. at 6:45 am. There were about eleven people waiting by the front door already. The guard opened the door at 7:05 am. After I went through the security and set in the waiting area, it was twenty after seven. There were five people waiting in the interview area. The rest was in for info pass or fingerprint.
Rajiv Khanna's office is very client-friendly and will understand the client's problems and work with them closely. This will ease the tensions/worries. And they are very prompt on updating the information to the clients.
