I agree w/ ur cousin. however, instead of bank statment, you and your cousin shoud have provided your refinance lender a LETTER from lender for student loan stating "loan is satisfied".
it is your refinance, not your cousin's. so your cousin is right.
這不是自私不自私的問題,關係到隱私權。 這是在米國, 應該不難理解。
好事多磨。 退一萬步,不成的話,接著打獵。
祝你好運!
