About Bank certificate & I-20

<p>I'm an international student. Two of my friends who got into MHC received the big package today and the letter said that they should send MHC a bank certificate showing you have the whole four years' fees to get an I-20.
I'm wondering whether Wellesley is asking for the same thing or simply asking for the first year's fee.</p>

<p>Anyone knows? Thank you so much.</p>
