Extensions of the South Korean eTA are not possible, as it is valid for up to two years or until your passport expires, with a maximum stay of 90 days per visit.
What You Need to Know
The South Korean eTA is intended for short-term visits such as tourism or business. It cannot be extended beyond the 90-day limit per entry, and you cannot change its terms once it is issued. If you wish to stay longer than the time allowed, you must apply for the appropriate visa type through a South Korean embassy or consulate before your trip.
Our Recommendation
Plan your stay according to the permitted duration of your eTA. If you expect to need more time in South Korea, contact the nearest South Korean embassy or consulate to apply for a visa that suits your travel purpose and length of stay.
A Quick Tip
Always check both the validity of your eTA and the maximum stay allowed before finalizing your travel plans to avoid overstaying.
