Good day and welcome to the forum! I think you are talking about a different ambassador program.
In this thread, we are specifically talking about Wayfarer Ambassadors. There is no location restriction afaik and global perspective is welcomed. Below is the announcement for last cohort’s call:
Community Ambassadors are separate and the focus is Campfire community events for Pokémon GO. Whereas Wayfarer Ambos are tied to the workings of the map that powers the attributed games.
