What this means for your trip
Visa-free entry lets you arrive with a valid passport and pass border control without applying in advance.
Border officers can still ask for a return or onward ticket, proof of accommodation and enough money for your stay, and they decide on entry. The stay limit applies per visit; many countries also cap total days within a period.
Your passport should normally be valid for at least six months beyond your planned departure date and have blank pages for stamps; many countries apply this rule.
