there are a lot of agencies that recruits nurses for kuwait at the moment. just google search..
anyhow, all government hospitals, that is under the ministry of health, are the best in terms of modernized equipments and renumeration packages.
since we are in the gulf, then its tax free; accomodation, food and transpostation is being provided by the sponsoring facility and the pay is more beneficial than that of private institutions, (although private hospitals also provides good benefits.)
anyway, best of luck!
