To add to this, you will need to show official proof of the ability to cover at least one year of your US university cost in order to get a visa to study at the university.
Students applying for an F-1 visa typically provide proof of funding for their first year from the following sources of funding:
- Personal funds
- Sponsor funds
- Government or sponsoring agency (includes CONACYT, etc.)
Universities will typically accept the following forms of financial proof from your sponsor(s):
- Bank account statements translated to English
- Proof of guaranteed loans
- Financial award letters
- Other official documents outlining liquid assets
If your family will use most of their resources to send you to boarding school, you may not be able to provide this proof needed for a visa. It is a very rare US university that will be need-blind for international students AND offer them enough to cover costs. There are literally currently SEVEN schools in the US that will do this (a few others, like Brown, are working toward it - class of 2029 for Brown).
