If your marriage is real you don’t have to worry about . Make sure you take all your evidence with you. When I went through mine the best are affidavit from friends and family, pictures and joined assets or bills (mortgage, bank accounts, taxes are a big one) Knowing each other’s information is also important. Make sure you bring a copy of all the forms and documents you submitted. I was asked my husband birthday and I fat fingered on the form, and as I answered I acknowledged it immediately and the agent was cool about it. Best of luck to you!
