My girlfriend feels lonely

So my girlfriend (24) is originally from Paris and made the big step to move to Switzerland (Biel/Bienne) to live together. She left a lot behind, which is super hard for her and she‘s feeling quite lonely recently. I understand her situation and support her as much as i can with any kind of activity but i think what she needs is a small group of friends to connect with. Do you guys know any way she could find people who are open to connect or just down to get a coffee sometimes?
