South Korean passport holders enter Vietnam visa-free for up to 45 days (extended from 15 days in August 2023). No fee, no advance application. Passport must be valid for at least 6 months beyond the date of entry. You need a return or onward ticket. The 45-day visa-free entry is single-entry. To re-enter Vietnam after leaving (for example, after a side trip to Cambodia or Laos), you need either a new 45-day visa-free entry (with a gap) or an e-visa.
For stays beyond 45 days, the e-visa at evisa.xuatnhapcanh.gov.vn costs $25, allows up to 90 days (single or multiple entry), and is processed within 3 working days. Extensions of the visa-free stay are possible at local immigration offices for about $10 to $25, adding 30 days. The e-visa is the cleaner option if you know you need more than 45 days.
