The rest of the trip for a Vietnamese passport, from the arrival form to customs and travelling with children: South Korea entry requirements.
The details for a Vietnamese passport.
Korean Embassy (Oman) visa-exemption list (country list dated 1 Apr 2016) shows Vietnam exempt only for diplomatic/official passports, so ordinary passports need a visa (short-term visit C-3) from a Korean mission or the Korea Visa Portal where e-visa is offered. Basic fee on that page: USD 40 single entry up to 90 days (fees vary by reciprocity; confirm with the mission). Jeju exception: 30 days visa-free on Jeju only, via direct international flight (K-ETA reportedly required; secondary source). Feb 2026: 5-year multiple-entry visas announced for prior visitors from Southeast Asia (no effective date).
How long it must be valid.
Visa-free tourist stays: passport must be valid beyond your departure date from Korea (no fixed minimum; US State Dept: 'no minimum expiration validity requirement'). Long-term visas: at least 6 months from arrival (FCDO). Passport must be undamaged (French MFA). Airlines may apply stricter rules.
