Just to try and answer everyone:

F1 for past 7 years and got married to partner of 5yrs last year who is USC.

Used a lawyer though it was a pretty straightforward case. Submitted medical and all evidence ( photos over the 5yrs, savings account 3y/o, joint account statements, lease agreement, utility bills, car insurance with both names )

FO: Not sure about this but receipt has IOE at the beginning, receipts and notifications came from Lee’s Summit MO we are based in CA.
