I came to Switzerland at the beginning of March 2010 but decided to leave in mid-July. So I de-registered, packed my bags and left Switzerland. Two weeks ago I came back for a short visit and now I am 100% sure that I will not stay in Switzerland. Here are my questions:

1. Once I leave Switzerland, is there anyway (preferably online sources) I can check to see if there is an outstanding bill for me? I asked the post office to forward my mails, but just in case I don't receive my mails or bills for that matter, how I can find out that I have some bills to pay here?

2. As a student at of the universities here, I got a B permit and a residency card with the expiration in Feb. 2011. Do I need to do anything about it? or does the deregistration and disenrollment from the school take cares of it?

Lastly, one curious occurrence: last week when I went to a money exchange office at CFF train station to send a western union, the clerk could still locate my registered address in the system when she searched for my name. Considering the fact that I de-registered back in July, that made me apprehensive. I mean why they still have me registered in the canton with my previous apartment address

Thanks to anonymous for the advice

Was the advice, just to leg it?

You can find out if you have any outstanding debts online here: https://www.e-service.admin.ch/eschk...index_html_de/

Your previous address will still be in many systems such as Directories, Search.ch and Twixtel for a while.

Thanks for the link! That should help me out also

I doubt the school will deregister your permit.

Personally I would keep the permit, and try and enjoy the forthcoming snow. If you are young, single, & money is tight, you could get a job in a Chocolate factory (very busy around now), a cheese factory, a Gold refinery (eg if you are a Chemist, or IT for process control), etc. Swiss companies are naturally finding it difficult to get cheap overseas temporary labour permit wise. Would be something cool & interesting to put on your CV.

Thanks for the link. I will also make use of it once I leave CH
