What will the visa officer ask for immigration to the United States?

I am in the same situation as you. When the visa officer asks, he will ask your mother what does the person who marries your mother do? Where does he live? Like what kind of house does he live in? When did he come back to see you? Where did you travel? And so on.

My mother and I didn't prepare anything for the first time, so we refused the visa. The second time I asked a lawyer to prepare the materials, it was successful.

In addition to understanding the above problems, we also prepared photos, correspondence records and letters of our lives for them to see.

In order to succeed, my stepfather remitted the money back to my mother's bank in China through the American bank, and then the bank would have a collection record. This is very important, because it can make visa officers more convinced that they are really married.

As for letters, my stepfather sends cards from time to time. When we receive them, we will take the envelope to the visa officer, because it has the names and addresses of the sender and the recipient, etc., so as to increase his opinion of your authenticity.

Personal experience' I hope it will help you.
