Next step **How we know** Access verified against an official source Stretch's rules pipeline checked the entry category against the destination's official publication and a reviewer signed it off. Stay length verified against an official source The stay length was checked against official evidence. Sources are listed further down the page. ## How the count works for Portuguese citizens in South Korea This is a rolling window, the kind that catches people out: on any given day, look back 180 days and count every day you were inside — that total must not exceed 90. Leaving does not reset it; days only fall out of the window as they age past 180 days. Stretch does this arithmetic for you every day and shows the days you have *now*, not the nominal maximum. ## Before you fly Stretch publishes no independently sourced arrival card or application checklist for this route. Use the official check labelled in the sources section before travelling. ## Notes from the rulebook Per the official source (www.k-eta.go.kr): 90 days in a row, not exceeding 90 days within 180 days Current K-ETA country table directly requires K-ETA for this visa-free route and displays allowed period of stay exactly as “90 days in a row, not exceeding 90 days within 180 days”. This text is intentionally not converted to days/window/reset fields. ## Sources - **Evidence for the rule:** Official: www.k-eta.go.kr — checked 2026-08-26 - **Official check:** [k-eta.go.kr](https://www.k-eta.go.kr/portal/guide/viewetaalification.do), retrieved 2026-08-21 - **Official check:** [k-eta.go.kr](https://www.k-eta.go.kr/portal/guide/viewetaapplication.do?locale=EN), retrieved 2026-08-26 ## Questions Portuguese citizens ask about South Korea **Can Portuguese citizens enter South Korea without a visa?** No visa, but an electronic travel authorisation is required before you fly. Access verified against an official source. **How long can Portuguese citizens stay in South Korea?** 90 days in any rolling 180-day window — stay length verified against an official source. Because this is a rolling window, leaving does not reset the count — days only drop out as they age past the window. **Do Portuguese citizens need to fill anything in before flying to South Korea?** Stretch publishes no independently sourced pre-travel paperwork for this route. Use the official check labelled in the sources section before travelling. **Is this South Korea rule verified?** Access verified against an official source. Stay length verified against an official source. Both public claims have cleared the publication bar. Last checked 26 August 2026. **How does Stretch keep count of a stay in South Korea?** Log the day you arrive and Stretch shows the days you have left and the date you must be out — reminders at 14, 7, 3 and 1 days, and on the day. For rolling windows it recomputes the window every day, so the number is the days you actually have now.
