Second-hand observation here: I know many international families who moved abroad with their kids at various ages; other than the language barrier that won't be an issue for your daughter, there wasn't much difference or extra parental concern necessary regardless of the country or school their child attended, regardless of their origin country.

Support, encouragement, listening to their kids, helping when necessary.

She'll probably assimilate into the local culture and customs with what seems like shocking ease. And she'll probably have the same troubles, trials and concerns that any student does regardless of which school they attend.

Is say the big thing will be making friends. Most of the others will already have friend groups. Others won't. If encourage them to join.activities or clubs in or out of school to help the friend process.
