[Update] The Korea-Singapore Vaccinated Travel Lane (VTL) is no longer in effect from 1 May 2022. Fully-Vaccinated Travelers entering the ROK can refer to the ROK Embassy in Singapore’s notice here for an overview on Quarantine-Free Travel to Korea.
The ROK has reinstated the visa waiver agreement with Singapore with effect from 8 November 2021. This means that Singapore passport holders are not required to apply for visas for short-term entry into the ROK (less than 90 days). They will instead be required to apply for a Korea Electronic Travel Authorisation (K-ETA) via www.k-eta.go.kr
For further information pertaining to entry into the ROK, please contact the Embassy of the Republic of Korea to the Republic of Singaporeat firstname.lastname@example.org
