Hi,
I had an interview today and it went all except that the FO assigned RFE on spot to prove our marriage valid. I am in F-1 Visa and my spouse came to the US on July-15 under F-2 visa as my dependent. Since she is in F-2 visa so she can't do much things here in the US and as she recently came here, we do not have things common here, such as joint account, joint credit cards, both of our names on store cards etc (of which he as giving examples of). But we have both of our's names on the lease (we live in university housing) and I turned that up to him today.
Now, the things that I am thinking to send are some more photos (he took some of them we had there but we did not have photos showing gathering in the marriage) of our marriage and photos that show us together before our marriage (we did MS together - classmates). The other thing I am sending is my plane ticket confirmation to my country which seems to be confirmed on 23rd January 2016, 4 months before my selection on DV. I guess he wants to be clear that there is not any relation between our marriage and my selection in DV (we got married on May 17 and which was planned before quite long time ago).
Any other suggestions? Thank you !
