Foreigners from countries with the visa-free regime can enter Serbia for treatment without additional visas, provided that their stay does not exceed 90 days. If a foreigner goes to Serbia for long-term treatment (more than three months), they should apply for a long-term visa (type D).

Foreigners traveling to Serbia under the visa regime must apply for a long-term visa for treatment abroad.

All persons traveling to Serbia for treatment are advised to indicate during the visa application process that the visa application is being submitted for medical reasons. Thus, consulate officials will be able to take into account the wishes and purpose of the applicant's trip at the beginning of the procedure and make a decision based on this information.

Please note that when crossing the border, border guards may request an invitation from the clinic or medical institution where you will be treated. An invitation (certificate) from a medical institution should be obtained before crossing the border.
