Need help...American Citizen marrying Polish Girl [52]
This couple. She a US citizen, he illegally overstayed his visa. They married. After about 6 months, they get appointment with the INS. They ask questions about the marriage, blah, blah, blah. Then he gets approved for a work permit. So now he can work legally. But, he was in the USA for 5 years and worked illegally, without a social security number. So even if she doesn't have a work permit, yes, she can still work. That can and is done all the time. Chicago is full of illegal immigrants. I know some, who have been here for over 20 years and still don't have a work permit. But once she is married to you, she would have to wait about 6 months to get a work permit and after about a year she will get a green card which is the same as an immigration card. And then in 3 years she can become a US citizen.
There are immigration lawyers who can help, but since you speak English, you don't need a lawyer and you can do it yourself.
You need to contact the USCIS. If you live in Colorado, then you need to contact the one that's in Nebraska. You can also call the Polish Consulate in Chicago at: 312-337-8166. Thay will give detailed information.
Your fiancee would have to file an adjustment of status at your local USCIS office, saying it was a "spur of the moment " basis, which means she didn't enter with intent to marry but decided after.
