Hi there
I am a Latvian in CH, too. There are some chances to work here officially (which might not be easier than the one, to wait until March), one is, to enroll in the university and find a job on the side of your studies (needs an extra permit then, but is not so difficult), the other one, to open up your own business. If it proves to be working, you will have a B permit for the extension of a few years
btw you can visit me on
www.yoga-joy.ch, this is the way I am staying here!
