Most of the colleges on your list are need aware for international students. This means that your financial need could be considered when your application for admission is reviewed. Even with the amount you indicated your family can pay, you would need more than $50,000 in aid at some of these colleges.
If you used the net price calculators to see if these schools would be affordable, please keep in mind that the NPCs are not always accurate for international students.
IIRC, Purdue doesn’t give need based aid to international students @momofboiler1 ??
In my opinion, you should only ED to a college that is your top choice. It sounds like you are not sure about that.
I think it’s good that you have identified some sure things in your home country and are considering those should a college in the U.S. not work out.
What do you plan to do after you graduate from undergrad? Remaining in the U.S. to work looks like it will be much more unlikely in the future, but that is an unknown right now. You should plan to return to your home country once your student visa here has expired.
You say you are a nominated for a scholarship at UT, but I don’t see that college on your list above. For those wondering, this UT is University of Toronto.
