In Germany with expired Schengen visa. Cannot return home due to coronavirus

The visa status should not prevent him from leaving Germany. Under normal circumstances overstays may be punished, but for people who leave on their own after a few days that would at most be a fine. That makes the response by the border police puzzling. Are you sure nothing was lost in translation?

The city of Munich writes:

• Contact the KVR before the visa expires. He has done that.
• He will receive a certification which is valid until the KVR reopens. That hasn't happened yet.
• If there is no reply yet, he should send a mail with scans of
  • Passport and visa
  • A confirmation of the hotel or host where he is staying.
  • A proof that departure is impossible. (They don't say what that is.)
  • If available, proof of health insurance.

So it seems that he did everything required and the city administration can't keep up.

He should take care to get everything documented properly so that there are no problems with the next Schengen visa application.

While I understand that returning home might be a personal emergency for him, I would think that Munich is reasonably safe at this time. Germany has more confirmed infections than Iran, but fatalities are fewer.

Hi everyone and thanks a lot for all your help

The problem got solved. My friend sent an email at 7:35 (the opening time was 7:30) and attached all the needed documents. He also mentioned that he contacted the border police and they have said that he can't leave without a visa. They sent him a certificate by email that shows he is allowed to stay because of the situation.
