My friend had a 15-days visa from France. His flight to Iran got canceled because of the coronavirus. After that, he came to Germany (Munich) because he had relatives here and went to the immigration office (KVR) to extend his visa. They told him that he can extend his visa but he should provide insurance. After providing insurance the immigration office got closed. He has sent several emails but he hasn't got any response yet. His visa is expired now and we are so worried about this issue. Is it possible for him to go back to Iran with an expired visa in this situation? The border police say that it's not possible and going back is an emergency now for him.
Do you have any suggestions for this situation?
