#2 - school - your child will more than likely have to go on the waiting list for a school. There are more options than just the 2 schools you mentioned. Have a look around when you get here and find one you like and get on the list. You will not want your kid going to a local school.

#4 - I had never lived outside the US before I moved here either. I think the biggest adjustment for me has been the landscape (or lack of)and the lack of a yard. Your wife can be a busy as she wants. Moms are always meeting for coffee or playdates. Tell her to check out the Qatar chatboard on expatwoman.com. Loads of information.

We don't regret the move and best of luck to you and your family.
