You might as well print out one recent mortgage statement, just in case. It could establish that you have a place to stay that is suitable for 3 people.
 
If you do a significant amount of spend on credit cards, you should print out a few months instead of just 1. In my opinion that would be pretty strong evidence.

I really really appreciated your help!!
Most of people have lot of evidence so, i am so worry about it;(
But i am glad that i could have another evidence! 

You are very welcome 😊

So helpful information!! I really appreciated. I will call them tomorrow. 

Hello, i have an appointment for the aos, they’re giving me only 15 days to prepare everything. I have everything except the copy of the packet we submitted (we either cant find the copies or didnt make any somehow) - also since i still dont get my work permit, i dont have a ssn so we dont have a lot of marriage evidence other than personal things like pictures. My husband has everything on his name since i dont have credit score or ssn. Would this be a problem? Thank you for the help!
