Hello,
I moved into Swiss last year in a L permit. I did not cover myself with a Health Insurance for close to 8 months as i assumed i would be back in my home country within 6 months. I took an insurance coverage only this year. Is there a possibility that this could pose an issue when i apply for my Workpermit renewal. Would i be asked to pay for all the months backdated or the worst, would the WP renewal get rejected ? Would they go to that level of tracking?
Thanks for your feedback.

This is a tricky one.

I've been asking around a bit and generally the answer is no, once you have proven your insurance then the history tends to be forgotten. This was the case with me - I had about 6 reminder letters before I did it, one a month, once I sent in the name of my insurance company I was left alone and has no problem renewing my permit and oving from an L to a B.

But, there is at least one example of a friend in Basel who had to backdate his insurance payments - however he did require medical treatment (which he paid for but was still asked for his insurance company which he didn't have) so I guess that may have triggered it off.

I think the final answer is you will have to take the risk and see what happens.
