I'm a Colombian minor, and next year I'm planning to move to the US to study at UOFWA in Seattle; in a few moments, I have a meeting with the person who will help me to continue with this process. The problem here is that, as I said, I'm a minor and I depend on my mother + I'd really like her to move to the US as it has a better life quality than Colombia.
She's 50 and has at least a B1 English level, she has also worked and lived in the US around the late 90s and early 2000s.
After days of searching, I haven't been able to find any way for her to get a green card without marrying, and we really want to make this process in, well, the legal way.
As I'm a minor, is there a way she can get a green card just by the fact that I depend on her economically? Like a guardian green card (if it exists) or something? Are there other ways of acquiring a green card? Like, by buying a house for example.
Thanks a lot.
