We would like to inform you that if you have sponsor in Bahrain, then he shall finished the work permit procedures on his sponsorship. If you don't have sponsor, then you can get the fixable work permit which allows the qualified person to work and reside in Bahrain without employer "sponsor" for 2 years and you can renew it. So you can work in any job and in any specialization with full or part time.
