Hello, I just applied for my mom's I-130. She currently lives in Korea and I live in the States. She was planning to come to the States just for a visit but we were wondering whether that would be possible. She has a job and a house. Would that be sufficient to show the immigration officers that she is willing to go back and is not going to stay longer illegally?
Also, I've seen people apply for I-130 and I-485 at the same time in the States, once their parents' travel visa expires. Isn't that illegal?
