we submitted our i-751 on november 19th. we included as much evidence as we could scrounge together: pictures of us together, two lease agreements from apartments we rented together, car registration in both of our names, two affidavits from my mom and my friend attesting to the veracity of our marriage, a bank statement from our joint bank account, among some other papers as well.
hoping for the best.
good luck to everyone in the thread!
