have you checked the NHA website? You have there the criteria for elegibility to practice as physician...u need to have at least 5 years postgrad experience to be able to sit on the exams conducted there...if u already have job offer here as company doctor, most companies will ask for your paper and have it evaluated by the NHA, then they will inform you regarding the next step...or you have to go there by yourself and present your certificates, fill up the form, sit on the exam, then oral exam...this is as far as i know...hope it helps
