I have read the whole thread. I got a B permit on the way (approved letter with me already), i am a Spanish citizen hired by a swiss company that made my paperwork.
My fiancee is swedish, we have lived together for 4 years in Spain and Sweden and now he is coming to Switzerland to look for a job. He can sure stay and look for a job for 3 months and extend the search for another 3 months, that is clear. But what happens if he doesnt find anything?
I met with the girl who takes care of that in my company today and asked her about my partner. She said i should NOT mention my partner when i go register to the city and that we should register separately. She said i should NOT try to talk to inmigration about him getting the B permit thru me because we are not married. He has to do his own. I wondered then if she was concerned that i'd loose my permit or something if i mention that i intend to bring my boyfriend???? I am guessing that it is impossible. I work for a swiss company and i have a B permit approved.

That got me confused and she didn't have any answers.

so...what would happen if he doesnt find a job in 6 months? Yes ok, go back to sweden without me but he DOES have the means to sustain himself over here even without me. How to prove those?

It kills me that even though we are partners (not documents signed though) and getting married next year, he cannot have permit from me.
In Sweden we are "Sambos", swedish government gives out residence permits if the two people live together as a couple.

So thing is, if he doesnt find a job in 6 months (and after being extended for some more) is there any other way to prevent him from leaving my side?

Thanks.
