We had our AOS interview at USCIS. We are a same sex couple and we were asked some basic questions about about each other, but we were asked a lot of questions about other issues. I am posting just in case any same sex couples out there prepping for interviews.
We did have the basic questions:
What is your spouse's birthday?
Where do you live?
Do you rent or own?
Who owns the house/leases the residence?
When did you move in together?
Whose phone number is this?
In addition to these questions, we had questions like:
When did you first know you were attracted to the same sex?
Did you ever date the opposite sex?
Were you ever married before? Apparently, state registered domestic partnerships also count if your state requires you to list them on the marriage certificate. My- I-130 application had to be changed to reflect formerly married - which was confusing since the Federal Govt does not recognize State Registered Domestic Partnerships.
The IO asked about dating history, and how long each relationship lasted
We took all of the listed documents as well as wedding pictures - you may want to bring duplicates of the photos, the IO asked to keep about 8 of our photos. We had all the standard documents like:
health insurance cards
auto Insurance cards
auto registration for jointly held vehicles
bank statements
loan statements
paystub for petitioner
dissolution order of previous domestic partnership
What we were asked for and did not have:
Joint cell phone account statement
College transcripts (AOS from F-1)
Paystubs for beneficiary
We did not receive an approval on site, but the USCIS site read "card production" at one point and now it went back to "decision"
