I married with my US citizen wife in March 2011. We want to apply for my AOS. She has a 7 years old daughter (US citizen) from her previous marriage.
She also applied for AOS for her husband (the father of her daughter) 3 years ago but thanks God she got divorced 1 year ago.
She is working as a waitress in one restaurant but she doesn't get pay checks, I believe she can't be my sponsor because she can't prove her income but her father assume to be our co-sponsor.
I have been told that our marriage can raise a lot of suspicion and scrutiny from USCIS but I don't care and we want to be together with our daughter.
How do I prove to USCIS that my marriage is real because at AOS interview the immigration officer might don't believe our relationship due to the facts I wrote above.
Thank you.P.S. My wife was born in US and left the country when she was 4 years old with her family to El Salvador and she came back to states when she was 12 years old. If we pass the interview we want to go to visit my country Romania and my parents to have their blessing.
