Vietnamese travelers can visit Jeju Island visa-free for up to 30 days if they meet specific entry requirements.[1][2] Based on your planned itinerary from Vietnam via Singapore to Jeju, here's what you need to know: ## Entry Requirements for Visa-Free Travel **Direct entry to Jeju is key.** You must enter Jeju through Jeju International Airport (CJU) or Jeju Port via air or sea route.[1] Your plan to fly Vietnam → Singapore → Jeju satisfies this requirement, as transiting through a third country like Singapore before arriving directly at Jeju Island is permitted.[2][5] **Essential documents to prepare:** - Valid passport with at least 6 months remaining validity[4] - Round-trip flight booking (proof you will depart the island)[4] - Hotel booking confirmation (proof of accommodation)[4] - Financial documentation if immigration officers request it[4] ## Important Restrictions **Stay within Jeju only.** You cannot travel to other regions of South Korea without a visa.[1][4] This is a critical limitation—if you leave Jeju to visit Seoul, Busan, or mainland Korea, you will need a South Korean visa.[1] **Maximum 30 days, non-extendable.** Your stay is capped at 30 days from entry date with no possibility to extend.[1][4] **Purpose must be tourism.** Your entry is valid only for tourism, leisure, or visiting relatives—not for work or study.[1] ## Practical Tips for Your Trip **Currency and transportation:** ATMs at the airport accept international cards for won withdrawal.[2] The Wowpass bus card can be purchased with Visa/Mastercard at the airport, and you've confirmed it works with your VCB debit card with Mastercard.[2] **Language preparation:** Basic English knowledge helps, though tourist areas are generally English-friendly.[2] Your itinerary is well-planned—direct entry to Jeju from Singapore, confirmed bookings, and understanding the 30-day limit puts you in good position for a smooth visa-free visit.
