I’m an American who was permanently living in the US until several years ago. I wanted to go to grad school, and my employer offered to pay 50%, as long as it was a related degree. I looked at programs in statistics (not my ideal, but it was a good overlap between programs my company would reimburse and ones that interested me) for a mid range state school nearby and it would have been something like $4-5k per semester out of my pocket all told.

For about double the cost to me per semester (so the standard full cost), I was able to buy plane tickets, cover visa fees and my entire cost of living for six months to study in my ideal program at a great university in Germany (it would be similarly expensive in many European countries and cheaper in many European or Asian countries).

The only reasons not to make that choice are that you don’t speak other languages (though many international programs are offered in English and even other anglophone countries have cheaper universities than the US) or that you’re too settled in the USA. If you’re not from the USA, what could possibly draw you there with an additional $100k fee?
