Please note that the mandatory health insurance requirement in Germany applies to you starting from the beginning of your first semester (October 1st for the winter semester, April 1st for the summer semester). It is essential that you clarify the potential implications with a statutory health insurance provider in Germany (e.g., Techniker Krankenkasse, AOK, DAK, etc.) if you are unable to enter Germany until the official start of the semester. If you fail to arrange statutory health insurance or obtain an official exemption from the mandatory insurance requirement in a timely manner, you risk incurring high costs in the form of retroactive payments. Therefore, please attend to this matter while still in your home country.
