Overseas Grad Studies for US Students?

foidulus asks: "I am currently a senior undergrad at Penn State looking into studying overseas. I spent 6 months working in Japan at an R&D lab and have published 1 paper with another pending publication(though I was researching security, however I would like to study bio-informatics). I am confident in my Japanese language skills, however it seems very tough to get any scholarships or funding there, but in the US a lot of schools seem to have tuition waivers and stipends(some even have health insurance!). Have any US Slashdot readers done any Masters/PhD work abroad? Do people from outside the US have any information on grad school in their country? What were your experiences? How did you get funding? Were your language skills adequate?" What differences can one expect when dealing with Graduate School in a foreign University compared to those in the United States?
