Our appointment was at 9 but we got there around 6:45. We Ubered there so we had to find a place to go leave our electronics and make copies. The office we went to is a block away, they tried to skyrocket prices for us so we said we’d go somewhere else and sure enough the price went down. We entered the line for residency. Once through security we went to sit in these outside benches, after about 30 minutes we entered the main building. They gave us a number as we walked in. In the new line this is where we gave them the medical records, passport, birth certificate, marriage certificate and appointment letter. We were then told to sit and wait. Our number was called and my husband was asked 4-5 questions. 3 minutes later we were approved. I was only asked if my husband had any children. Our official was very nice and she laughed with us. Just smile, be happy, and tell the truth. It didn’t even feel like we waited 3 hours. The whole process is very organized!
