<p>Note that Oberlin claims to meet 100% of documented need, but they do not claim to be need blind in admissions. </p>
<p>That suggests:</p>
<p>a) If they accept you, they feel that they have provided enough aid for you to attend based on the financial numbers that you gave them. Unless you can document the additional need between what they think is enough and what you think is enough, they may not be very happy with you for backing out of an ED acceptance.</p>
<p>b) If you can document the additional need, there is a good possibility that they will give you a better FA package, particularly if you appeal early enough in the admissions cycle before they have committed all of their available FA funding.</p>
<p>c) The bar for acceptance may be somewhat higher for those who need a full ride or something close to it, particularly if they also happen to be international students, than it would be for a domestic student who needs only a fraction of that amount to be able to attend.</p>
<p>Also consider that Oberlin is one of not many US schools that offers aid in large amounts to international students. If what Oberlin comes up with is insufficient, it may be hard to find a better deal.</p>
