Hi. I am currently a senior nsg student in a 4 year program. I happen to have had more than a smidge of experience with the Middle East, although not via nursing. I lived in Egypt for 4 years, went to school there and taught English to Egyptian kids in the villages while I was there. I lived alone and did not have room mates, which made me a kind of target for any errant male that passed by, as women do not live alone in the Middle East. They either live in the homes of their husbands or their fathers. Bottom line is, a male must be responsible for you as single females are considered to be like loose cannons and willing to sleep with anyone if the opportunity presents. This is especially true in their view of foreign women. The Koran says that women must keep their hair covered at all times (which I did not) or otherwise they are considered to be naked and more or less of a prostitute. Whether they are or not. A woman with uncovered hair will be followed by men in the street who will attempt to talk to her and even touch her because they figure it is O.K.
In Saudi Arabia, from what I have heard from nurses and other women I know who have worked and lived there, the following applies:
1. Unless you are a Muslim, you are an infidel (unbeliever). Since Saudi Arabia is where the Holy Site of Mecca is, as an infidel you will not be allowed much freedom on the streets. You will be basically confined to an enclosed area where all the Western and other foreign people live. This is where your hospital will be also. You will be able to wear Western clothes there and will not have to cover your head. You will have a commissary there where you will be able to obtain all your favorite U.S. products, like Cheerios, that are not available once you step outside the compound.
2. If for some reason you do go outside the compound, you must wear "hejab". This means approved clothing for Muslim women. You must be covered head to toe in a dark "burka" and your face and hair must be covered as well. When I was there, women were not allowed to drive in Saudi Arabia. The rationale given for this was that if they got a flat tire that they might have to remove their veil to fix it and this could not be allowed as the society would come to pieces. So, unless things have changed, women cannot drive.
3. The vast plus to all this is that, whatever money you make, there will be precious few places to spend it. So you will wind up saving a great deal of it.
If you feel you can stand being somewhat of a prisoner, then go for it. Given what the economy is here in this country, and the fact that you will be able to save most of what you make when you get there, it might not be a bad experience for you. It also looks great on a resume.
