1. Yes, definitely- however, the UK university MUST have a FAFSA school code (most do, but there are a few notable exceptions!). You can check to see if they have one on the FAFSA web site.
2. I'm fairly certain that you cannot use Pell grants (or any gov't grants actually, or Perkins loans) overseas...just Stafford and PLUS loans.
3. nope, not really. Individual unis may have partial scholarships for international students- check the British Council's website or university websites for more info.
4. If you can't get private loans and you don't already have a lot of cash (or a sponsor/parent willing to help you out), it's going to be difficult, especially for undergrads. Undergraduate Stafford loans will probably not even cover tuition, let alone the living expenses money you need to prove that you have access to in order to clear immigration. (You're going to need to prove you have access to ~ $30,000/year- for tuition, accommodation, and other expenses- to get a student visa.) Your parents can take out a PLUS loan, however, to fund the difference between the Stafford loans and the total cost of education.
