I have been studying in Germany since 2009. In Germany, in order to continue being enrolled at a university as international student, you have to have a health insurance which costs you around 80 Euros per month (in my case AOK). After finishing my Bachelor degree I went for one year in Asia for an exchange program (my first Masters year). Unfortunately I had to pay the insurance in South Korea (the German one doesn't offer long term travel insurance) and continue to pay the insurance in Germany in order to keep my enrolled status. Those were 12x80 Euros wasted, which is not a small amount of money.
Now again I'm back to Asia for an internship which will last one year and I really don't want to keep paying an insurance I don't use in Germany. Is somebody familiar with this experience? Is there any way to avoid paying while I am not in Germany and without being kicked out from university?
