Finding a job in Sweden as a foreigner is quite tough to be honest, I speak from my own experience. Unless you speak the language, have a skillset that is in high demand or have years of experience and are applying to very senior positions. OR, as usual, unless you have contacts.
I don't know to what jobs he is applying but there aren't that many for which he is really competitive or qualified for. Of course he could always find some odd job in retail, factory, etc., but I don't think this is what he is aiming for and even then, it isn't that easy.
My bet is that Rachel's dad will hook him up somewhere.
