Hello all, I have been a US citizen for close to 10 years. I never applied to bring my parents over, as they never showed interest in relocating to the US. But we have been thinking about this lately, as they would like to be close to us. They will be visiting the US for the first time on visitor visas soon. I have couple of questions, if I may: 1) As I understand, we can apply for adjustment of status (I-485) 90 days after arrival, correct, if we decide to pursue it? 2) Would we also need to submit the I-130 form? 3) Do they need to stay in the country while the adjustment of status is in progress and how long will it take to get the green card? 4) Would it be better if we apply after they return back home? We could possibly submit the I-130 form while they are in the US, if that is allowed, since they will be here for about 4 months. Thank you!
