As I know there are many of people who work there they live in Alkhor which is a small village close to Ras Laffan, but also alot of them lives in Doha (about 100KM away).

If you want to live in Doha then let me know so I can help you finding a nice accomodation according to your budget, you need to know that it cost alot now so you will have to ask for a reasonable accomodation allowence.
