If you are emancipated in the US and move to UK will emancipation still be valid?

The answer is: no

Emancipation is a legal process that is recognized in the United States. It allows a minor to become legally independent of their parents or guardians. However, emancipation is not recognized in all countries. As a result, someone who moves to the UK after being emancipated will not be emancipated. They will have to go through the legal process of emancipation in the UK if they want to become legally independent.
