The 5500US$ is "all inclusive" salary??

Ras Laffan: either you live in doha and travel on a daily basis, or you live in Al Khor and also travel daily but shorter time.

Depending on the company you might get housing in doha and then make your way to RLIC every day. Even you could get some transportation from the company. You will have to check with them.

I would suggest to you to follow the link
