According to this German News article , Concealed Muslims who are trying to get service from their Swiss town administration will get a rejection. Reason for this was an incident that happened at the town administration a few days ago. A totally concealed Muslim woman (according to the worker there: “You could not see her hand! “) wanted to register.
The worker refused but she offered her a new appointment for the next day. The concealed Muslim woman went then to a police officer and a residents’ registration office worker to get unveiled. But according to them they thought it was a too huge effort.
And they also say “We need to know who this is “face to face”.” So therefore there will be no service to concealed persons.
