Hello all...

Please accpet my apologies if this question has been covered before elsewhere but it's just a quick enquiry:

My girlfriend intends to come and stay with me for good in Zurich after she has finished her studies in the UK. She is full English and has a British passport. While she is looking for a job in Zurich and while she is staying with me being non-Swiss resident, does she have to obtain health insurance or is this optional? I know that if you become resident and have a job, health insurance is mandatory, but what happens during the period while she is looking for a job while staying with me as a visitor?
