I've a query about the source of funding for I-20 and Visa purpose..
As my University doesn't accept Loan sanction letters as accepted forms of funding, I'm trying to show the total amount in my savings account( By taking a personal loan)
However, I'm planning to take an education loan finally..

I'm planning to pay back the personal loan amount immediately if I get my I-20 approved from the college

So during Visa interview, is it necessary that I show the same savings account statement sent to college for I-20 ? (or) Will the Loan sanction letter alone is sufficient during Visa interview
