Immigration Site

So I asked my now fiance to marry me on October 25th (day after my birthday). Now we are in the process of figuring out all the immigration work to get her a green card so she can go visit home then return to go to school with me. She came here on a J-1 visa from Germany which expired on October 9th. She speaks English great, we have a lot in common, and she is less than one year younger than me. Really no problems there, from everything I read we have a very simple case.

Questions:

1. She ended up leaving the agency she worked for and began to work illegally. While filing the paper work and the interview I know NOT to lie, but she is afraid her previous employers will get in trouble (and me too considering my uncle is one of them). Does the USCIS connect the dots on this and get these people in trouble?

2. She never intended to stay in the U.S. or ever retuning in the future, thus she opted to not pay taxes while she was legally employed by the agency that represented her. I read back taxes are forgiven on marriages through green card, whats the best way to deal with that?

Thank you EVERYONE that responds!!!

1-Unauthorized work is forgiven to spouses of US citizens so she will be fine on that level.
2- I dont know about that, but Im guessing eventually she would have to pay taxes, someone more knowledgeable can help you with this one. Good luck

i realize that unathorized work is forgiven, but what about the people that employed her. She doesnt want them to get in trouble

I dont think USCIS will go after them. If they went after everyone who employed unauthorized workers, almost all companies would go bankrupt!
