Check out
www.iapsg.com and
www.ssnap.info and contact the parents there for more advice on schools - join their mailing lists for updates on programs and schools. You may not find the kind of educational support you would find in the US, as the situation for SN kids tends to change according to how full the
International Schools are. The fuller they are, the less they are interested in enrolling kids who need a bit of extra support. There are lots of international families here already with children with mild AS who will be happy to help you. Mods, these are voluntary support groups run for and by parents of SN kids.
