Most schools' front office staff are probably on holiday at this point. Maybe 2nd or 3rd week of August they will be back and getting things going. I'm only guessing here.

American School of Doha is the only on that possibly gives priority to American citizens. Might want to try Compass International School and International School of London. ISL is new and I have recently heard of kids getting into both schools. Your kids might have to sit out for awhile. Consider a temp. learning center, some form of home schooling and/or a school you don't really prefer just while your kids hang out on multiple wait lists. It is unbelievably frustrating but there's no real solution. Good luck.
