<p>I’d suggest that you contact Williams math department directly. I’m sure this is a concern that they’ve dealt with before.</p>
<p>Williams is not need blind for internationals, but they are international friendly and generous with need based aid. The key point is to determine how much need based aid you might be eligible for. If you qualify for enough to make it work for you and you are accepted, then the chance is good that you will be able to attend. Ask your parents to use an online calculator to get an idea of where you stand.</p>
<p>I would say that Williams is somewhat more selective than the other colleges you list, but your international status may actually work to your advantage. Williams, like many small LACs that are not located in urban environments, often uses internationals to beef up their diversity percentages. This is also true of some excellent LACs in the midwest and south. The key here is to be of the demographic that they are looking for, e.g., not White, not Christian or Jewish</p>
