My wife has entered US in 2000 on tourist visa and overstayed for 7 years illegally. I'm a US citizen, married her 11/08, went to interview 04/09 she got temporary GC and literally couple of weeks later I've learned the she went on vacation with her x-boyfriend for 4 days while telling me she had a baby-sitting job....nice, right? We didn't even go on our honeymoon and I get this -Soooo - our further union is out of the question and I'm filing for divorce as no family will ever happen neither I want to be responsible for this person after what happen.
The question is how will my divorce affect my responsibility for her because of beneficiary paperwork I've signed and what are her options will be?
I understand she can have my last name until her temp GC expires in two years, re-marry or whatever, but I want no business with this person anymore ever.
