I am a US citizen working for a UN agency with a temporary contract (Carte de legitimation G). Because of COVID, it seems that several EU countries such as Greece currently only allow US citizens with "permanent residency" in Schengen to travel to their country. Even if i took a direct flight and didn't have to go through Immigration, there are addtional forms now to fill out (such as health declarations).
Does anyone know the specific rules in this situation? Many thanks!
