Qatar visa process

Hello everyone, Iam saggy living in singapore past 7years and work in an hospital, singapore is a clean and safe place to stay and the only draw back is the accomadation, it's very expensive and have to share it with someone else.
Now I have got a job offer in Doha qatar and would like to migrate over there.
Could you please give me the visa details and the cost of living in there.

I would suggest visit Qatar embassy here to get the details or Google it or post your query in Qatar thread.

Thank you
