As everyone knows, an LLM in the States is hugely expensive. I really want to do it, but I'm naturally reluctant to get into $70000 worth of debt.

Does anyone have any tips on how to get funding?

ask the "3 F": family, friends and fools -- and buy knock-out warrants!

Look different types of international scholarship programs (Muskie, Fulbright....). Probably government agencies could finance your education and look which US Universities provide financial support/ scholarships. I know NYU, Harvard, Columbia provide some financial support like tuition waiver, scholarship or loan.
