Don't feel stupid. I'm so confused with FAFSA. My mom is filling it out because she has the tax returns, bank statements, etc., and it would just be easier to fill it out state-side, as I'm already at uni right now. I'm applying for loans for my second and third year of uni here, as I'm in my first year. I got a few scholarships for my first year of study from my highschool, which is helping me out for the first year.
I absolutely hate the lack of scholarship availability for US students here. Right after I got into the uni, they posted a new scholarship on the international website -- £3,000 for three years off the tuition price, which is basically a year free. Turns out that it was introduced because of an increase in American interest (uh, me, and the 0 other American full time students I've seen here in the undergraduate programmes!) and it's only available for people who haven't yet started. The only scholarships that were available when I applied were for refugees and people from Asia.
Frustrating.
However, the international office is somewhat sympathetic to this and are very good with the FAFSA information, etc. If you need any advice/help from your Uni, just email the Univeristy of Manchester international department (or if you need to, call them). At least in Nottingham they're very quick with replies and useful information. Should be the same case at Manchester.
