I go to college in America. I used to have an F/KLOC-0 visa, but now I just got a temporary green card. My parents give me living expenses every year. Do I need to declare tax?

Your identity is that you don't need to leave the schedule, and the schedule doesn't matter inside or outside. First of all, I- 130 (immigration application) can be submitted immediately after marriage and green card, but if you want your second-line to have the will to apply for approval, then you can submit I-485 (green card application). Before you submit I485, you must keep your legal status, that is, your F- 1, but once you submit I-65438, if you leave, you can't rely on the F- 1 project, because F- 1 non-immigrant visas are not allowed to have immigration tendency, so you can only have 485 in the United States. It is currently scheduled for June 20 10. Once 485 is submitted, you don't need to rely on it to maintain the identity of F- 1. If you want to return to the United States through the file, this is I- 13 1. So, there's nothing to worry about when you leave. I won't leave America for six months at most. The situation is just like you and me, but I am H- 1, and I am allowed to emigrate, so I have more convenient visits than you.
