I can not exactly quote the salary you will get if you work as a nurse in Dubai,but what I can tell you is that it will be good amount and working for seven to eight hours,will be your routine.
Nurses are needed everywhere; you should be able to command premium salary and good benefits at reasonable working hours. Dubai is not the only possibility.
I would think nurses are needed everywhere. Its just one of those professions. Look at any country or city, I think nurses would be one of the jobs with most demand, because they have a very important job. They do a lot of things and different nurses specialize in different things, but they are generally always in need of. Its one of those jobs that are overlooked but very important nonetheless.
There's a demand for nurse's job all over the world. To make a reasonable living in a city like Dubai, one should get atleast 3-4 k. Everywhere, duty time is around 7-8 hrs.
