Our appointment was for 7:30am and we showed up at 7:00 and waited in line. The information kiosk looked at our passports and let us in. We checked in our bag and cell phones and took whatever documents we had bought to the waiting area. The waiting area reminded me of a DMV line and basically it functioned just like one. We took our number which ended up being 11 out of the 11 k-1 applicants that day. First they called us up to collect our documents. The grumpy Khmer clerk took the police records, physical exam, visa payment reciept, I-34, tax return for the last year and our evidence of relationship. That was it. We had bought a bunch of other stuff concerning financials and original divorce docs but she didn't take any of it.
