To study in Germany or Italy how many months of health insurance is required for visa purpose?

In most cases, applicants are required to provide a health insurance certificate for at least the first 3 months of their stay. However, some of the embassies abroad might also require you to be covered for a period of 6 months after entry.

At best, you need to have unlimited coverage offered by your health insurance provider.
