Health insurance plan for your stay in Germany
If you want to study in Germany, it is mandatory to have a health insurance plan. Depending on where you are from, it may be that your public health insurance plan of your origin country is also valid in Germany.
Public and private health insurance
In Germany, there are different types of health insurance: governmental and private health insurance. While the contributions of the governmental health insurance are normally based on income, the contributions of the private health insurance depend on state of health, age, and the scope of the service/benefits you choose. However, German governmental health insurance providers are offering affordable security plans for (international) students up to an age of 30 or until the end of their 14th academic semester.
Health insurance plans
Depending on if you are planning to attend a preparatory course (Studienkolleg) or directly start your studies at a university, there are different options for health insurance plans:
If you apply to Studienkolleg or a language course
If you are not from one of the countries mentioned above and want to apply to Studienkolleg or language course, you are not eligible for governmental health insurance, since you are not enrolled in a university.
This is why you need to get a private health insurance for the duration of your studies. Note that you cannot switch to a governmental health insurance once you got covered by a private health insurance.
