You can work as a nurse here, you will need to register with the NHA so bring original certificates, transcripts etc etc with you. If you get a job once you have arrived you will get no benefits as you will be local hire. Try and get a contract from home - not easy as most of the reqruitment is done in the Philipines and India.

What sort of nursing do you do? If you have orthopedic experience try Aspetar Hospital, a new orthopedic and sports injury hospital, they have a large proportion of western nurses, great working hours but I am not sure what the pay is like - this varies according to you nationality( I know it is crazy) and whether contraceted from Overseas or are local hire.
