Your employer has the complete discretion on whether or not you can get a multiple -exit visa. But applying for each exit visa usually isn't a real problem. Make sure you get your holidays spelled out or you won't be doing much traveling! Your employer will pay for your visa, exit permits, etc. Yes, the salaries you see are for real. Hotels are notoriously cheap. An American friend of mine with a masters degree was offered $2.12 hour for full-time management.
