I am the petitioner. They ask me to prove my US Domicile since on the I-130 I said I lived outside the US. On the form I put a different address from the one I had. And now I changed my address and I want to know if the change of address confirmation will help, or maybe a letter from my old school, or registering to vote since I also changed the address of my license. All this I did it online because I am out of the US. What else can I do if I' m not in the us to get a bank account or things like that! Thank you for your time.
