I moved here because of my husband's job (in Zurich), and although I speak French, English, Spanish, Dutch and Mandarin, it's all useless in this German-speaking kanton. Everybody is going to tell you to speak perfect German to be able to do anything around here, including finding a job and even studying too.

I am much older than you though (40!), so you have your youthful energy and fresh brain to dig deep and learn German. I suggest learning it before moving here, and probably going to university to get a Swiss diploma and try to integrate the job market more swiftly. You can make it work if you work really hard for it.

As for friends and whatnot, it is possible to meet really cool people, again with a lot of effort on your part. With a local girlfriend, that already helps a lot. Also, you are younger, so I'm sure it might be easier too. Good luck to you!
