Ummm, research long and hard about the schools.  There are two new schools  opening this summer, but don't know much about them.  Have a co-worker who went through all the expense and trouble of bringing 4 kids to Doha, only to not be able to find a school position for ANY of them.  Quit and is leaving after only 8 months and great expense because of the lack of schooling.  It is very much something to think  about.
