Health insurance is not only required in Germany to acquire your visa but also essential for your wellbeing. If you are moving to Aachen for a job, your new company will likely be sponsoring your visa and will help you set up your public health insurance. As a student, your University and your residence permit application will require you to show proof of Health Insurance. If you’re a student and you’re under 30, you can join a public health insurance plan at a reduced rate.
