Nursing in Qatar is not easy. There are only 4 hospitals and Hammad Medical Centre, the public hospital here, is the only place she can get a job in a proper ICU. If you go to the Hamad website there is some info there. The hiring process in Hamad is very lengthy. She can also apply to Al Ahli Hospital - A private hospital, I believe they have a website too. I am not sure what the pay for nurses is like in Malaysia but it is not that great here and they only accept full time which is 48hrs a week.
There have been some threads about nursing before - do a search.
