Hi, all. Pretty tough situation ahead. I've met my current girlfriend about 6 years ago. She came to the U.S. on a K-1 that ultimately never lead to a marriage, and she has been here illegally ever since (10+ years). She was pregnant when she got here, and now has a USC daughter. We were talking about getting married, but I never thought this was going to be such an arduous task. From what I've gathered, she can't AOS in the country and we'd have to file for a I-601 waiver that's extremely hard to get, then leave the country and adjust from her consulate. Am I getting the gist of this correctly? I assume having a daughter does not give her any kind of advantage in this situation. She also runs a business here that requires here to be "at work" daily and cannot be done online. Are there any other options? I will be calling an immigration attorney on Monday, but wanted to check in with this community as well. Appreciate it!
