Hi everyone, I hope this post finds you well.

I need all the information about how to move and live with my girlfriend in Switzerland, but except for getting married.
She is living in St. Gallen and she's working there as well, we've been together for almost 3 years we have been traveling in Europe, Asia, and North Africa but now she's back in Switzerland and I want to go live with her. Thanks everyone in advance.

P.S. I'm not a citizen of the EU
