I got a job offer from Muscat. I have signed it allready. Didn't go for a visit. Just looked at info at Omanforum.com. Great site!
Also got lots of info from people that have worked there and people in Abu Dhabi that I know, not the same place but similar culture.
If you have an open mind for changes and experience something new it can't be anything but good thing to do, at least for few years
