I would suggest either trying to look for a recruitement agency or looking on the hospital websites under their careers. It's much easier if you have a job already. You can't register with the DHA until you have an offer
Hi! If your place conducts prometric examination for dubai, it would be easier for you. So by the time you get in here you'll just chose a field that you want. They require at least 2 years of nursing experience to be able to hold your license. Or you can visit dha.gov.ae for further inquiry.
