<p>Based on the clarifications, OP and his mother have valid green cards. Hence both of them can return to the US and settle in any state of their choice and they have chosen Michigan. Assuming that decision is now made, the question is what is the best way to get in-state tuition, given the fact that OP’s mother intends to make Michigan her residence and live in the community, pay taxes etc. Given the various posts, it does not appear that he will get it in his first year of college and he has to go through a lot of hoops but could possibly get it in the second year. Other choices include gap year or going to CC and then transfering.</p>

<p>Yes, if it had been clear that OP’s mom had green card, then I would not have suggested the work visa. It appeared from earlier posts that OP’s mom did not have a green card and hence the only she could work in the US is if she got a work visa. Green card holders cannot sponsor parents, citizens can, so if OP is not a citizen he cannot sponsor his mother.</p>
