I am a US born citizen, and I'm a sophomore in college, turning 21 in a couple of days. My girlfriend came on a tourist visa and overstayed. She's a freshman and 19 right now. Her family has been denied a green card twice (Once while their visa was valid, and once three years ago because they didn't fit one of the standards to get a green card under some new law. She was able to get a social security number and temporary working permit that expired within a year.)
My question is, are there any troubles for proving that the marriage will be legitimate based on our age? I feel like we would get married anyway, it's just that I want to help her a little sooner, as soon as possible. As to the affidavit problem, I have an uncle who is a US citizen who agreed to be our sponsor. Do you think I can help her out?
