Please house. I need an answer

I am an experienced and certified teacher. I have a masters degree in education. A bilingual school In Oman asked for my CV. I told the school that I can only join her team, if the working condition is right. I told the school to process my visa, pay my flight ticket, provide accommodation, health insurance and yearly return flight tickets. But am scared, because of all I have been hearing that NIGERIAN FEMALES experience in Oman. Please house, the question is, IS IT SAFE FOR A NIGERIAN LADY TO WORK AS A TEACHER IN OMAN?
