My advice: Don't agonize over this. A simple, short and straightforward letter from your college ko principal (or someone else in some recognizably authoritative position) on an official stationery on your behalf should work fine. Fax/send/mail that letter to all the schools you are applying to. [If in Nepal, you can probably get a sample letter from the American Center in Gyaneswor.] Good luck. oohi ashu
