We got to USCIS office in Irving, TX 30 minutes before appointment. By the time we went through security, and checked in it was interview time. The place was packed, but the office seemed organized. 30 minutes later we got called in by the officer.
She took us inside, and checked paper work. she then asked if we have any updated documents/joint assets we want to share. (I offered the latest IRS return, and couple of bills).
Officer then started asking how we met, and other I-485 questions (Are you a spy? Illegal gambling etc...)
The whole thing lasted about 10 minutes, and afterwards Officer said Congrats Y'all should expect the 2 Year Card within 4-8 weeks. When I asked if we can get a temporary Green Card Stamp in Passport, the officer said that we need to have urgent circumstances for that, and ask for an Info Pass.
Overall a Positive Experience, and a very professional Officer.
Good Luck Y'all
