You would only put the interest paid on the student loan as a deduction.
There is no requirement that the student loan is held by a US bank in order to deduct the interest. However, there is a requirement that the proceeds of the loan were taken out to pay “qualified higher education expenses” and, in turn, one of the requirements of qualified expenses is that the school be an "eligible educational institution."

- For education provided during an academic period for an eligible student; and
