In the Netherlands where I live all those questions are answered in a mandatory fashion. We have to have health insurance.
I once traveled to the US to study for 6 months and you had to bring a letter pertaining to the coverage of your health insurance.
I got called into the university's international office. They thought my letter was fake because it said all costs would be covered. Which it in fact said, and it was also true....
Hahaha! That's incredible. I bet the University officials must have been taken aback!
I have to say I love the Netherlands. I spent couple of weeks there last year and maybe come back for more vacation days this year. I have some great Dutch friends from there!
