About education: I do not know much about US education system since I did not have kids when I was there. However, from what I have seen in India, I feel that the options are very good for school education. ICSE, IB and IGCSE boards offer a lot of options that follow a US style education. For higher education, the funnel of options narrows down and the competition increases.
