YaY

Preparation for marriage all done.
Plan is to get the official marriage in the next weeks.

Can someone tell me how long it takes for me to get the B Permit in Kanton Bern ?

Do I need the permit in hand before applying for Jobs ?

you're EU so as it stands have a right to free movement in the EU. So you just need to make your nationality clear in your applications.

YaY indeed.
