Hello Candinhoss,
Okay working in The Bahamas is a tricky one, there are work permit requirements involved. I would suggest you look in the bahamaslocal website, its an online directory for physiotherapists and contact them directly about their staffing needs and willingness to apply for a work permit for you girlfriend. Ofcourse have resume and cover letter ready. The process is, she gets a job offer from an office here who then applies to Immigration for a work permit for her. The fees are quite high and it can take some time. If she is a trained teacher or nurse it will be much easier as The Government is usually hiring in these areas. Good luck.
