Need blind- means your finances are not considered when you are evaluated for admission. That does NOT mean the financial package is going to be affordable for your family! That’s called “meets full need”, and there are only two handfuls of schools which meet full need for internationals.
You need to understand how college financing works in the US before you get too far down this road. There are lots of colleges which are need blind for admission, give VERY generous aid (to domestic students) which are generally unaffordable for internationals who are not full pay.
I’m sure in your own country there are differentials between what citizens pay and non-citizens pay for university…
