I am a US citizen and I have submitted an I-130 (petition for alien relative) application for my daughter who is married and over 21. I understand it takes many years(not sure how many) for the application to become current but can anyone tell me how to help her prepare for what's coming. I am just afraid the application will be denied due to her illegal status. She is married and has 2 children born in the USA. One of them is 15 and the other is only 4 years old. She's always been a hard-working and responsible person and does not have a criminal history other than she was caught one time like 15 years ago illegally crossing the border.
