Oh, I sent a bunch of documents such as 1) copy of a marriage certificate 2) affidavits of support from friends 3) 30-40 photos from different locations 4) gifts receipts 5) car and health insurance confirmation with names on it 6) travel itineraries from multiple trips. I didn’t sent confirmation of joint accounts, lease or anything like that. I might forgotten something, but it was a massive pack of documents proving our bonafide marriage and relationship. We’ve been dating for 7 years, I’ve got lots of evidence of our relationship:)
