“Do not take loans for 200k+.”
For an international student going to school in the US, they have to assume that after graduation they will need to return to their home country. Unlike some other countries, the US does not provide work visas for foreign students who graduate from university – instead it is assumed that students will go home pretty much immediately after graduation.
As such, if you are from a country where $2,500 per year is the typical cost of attendance for university, then I would say: Do not take loans for more than $10k total over 4 years, and do not take loans at all if you can possibly avoid them. And, @lookingforward is correct that $200k in loans, while probably impossible and catastrophic for most of us, might be necessary to attend university in the US.
