Is a Greek visa needed to enter into a cohabitation agreement with my Greek partner?
I'm looking into a cohabitation agreement with my Greek partner (I'm an American citizen with no Greek visa.) If we apply for this agreement, can I freely live in Greece without a visa? Or do I need a visa and a cohabitation agreement to live in Greece with my partner full-time?
