I'm sorry that all this is happenning to you and I hope you people can find an honest partner in the future. Maybe this advice will help:
I am an immigrant from Colombia, I dated a boy a little younger than me at the end of my high school year and most of college. My immigration situation was not very clear...I was an entrepreneur's dependant, and my visa would expire on my 21st birthday...I was 18 back then.
I turned 19, i was right in the middle of college, in loooove and my parents were driving me crazy! So we eloped (: and we're still happily married to this day. We also decided that he was going to help me get my citizenship, because even though I was legal, and I could get a student visa, a student visa doesnt allow you to work, or it does but not full time, and the process through marriage was a lot faster, and! my visa would expire a cou. So a few days after we married, we submitted my papers. I am 21 now. Some of us actually do love our citizen partners, so, no hating on immigrants!!
But what I know about my case should help you out. In order for me to get my conditions removed from my visa I have to prove (according to my lawyer) that I have been married to him and that we are a genuine marriage happy couple kinda thing. He needs to know eeeverything about me...I dont know if for your interview it was the same, but my first interview they asked him what kind of birth control i used...they asked really intimate things that only a hubbie would know. We also had to submit proof that we were living together...it was soo much that we just decided to save ALL our mail saved. They asked us for things like...evidence of joint ownership (we're young, broke students, we dont own anything, so we cant submit anything like that) all this stuff that needed to show that we were together legitimately.
I'm thinking that with how strict immigration regulations are today...they're probably going to ask a LOT more from you people and from your misbehaved spouses. This is the opportunity for you to speak up and declare that you marriage was a fraud, that you were used and that you no longer want to claim citizenship of your spouse, citizenship will be denied and they will no longer have status = be illegal and eligible for deportation. then again, there is also a chance that...since things are so backed up in immigration, that they just stamp her visa, no questions asked, no interview, no nothing. But if she does get that appointment, usually the same month when her temp visa expires, show up and speak up!
Now, I am by no means justifying what your spouses did. It's horrible to use someone in that way. But think about what your motives are for doing what you plan on doing....is it revenge? or is it a real concern for the law? Is the burden of knowing that you ended with somebody's life as they know it, something that you're willing to carry forever? (I think about this when I get in a fight with my husband, I think that whatever our problem is, we need to solve it because we can't get a divorce; if he left me, not only would it break my heart, he would do away with my life as I know it, I've been here since I was 12! I have my family here, my degree, my job my friends, my life! and he also thinks about that, that even if things dont work out between us, since we married so young and we are so broke, he couldnt deal with his conscience if he f**** me over like that...) so think about what you're gonna do...and i hope things get better!
