If your K-ETA application is denied, you will not be allowed to board your flight or enter Korea. Denials may result from incorrect personal information, unclear travel purposes, or passport issues. You can reapply after reviewing the reason for rejection and correcting any mistakes. Submitting the same information without changes may lead to repeated denial. To increase your chances of approval, it’s important to double-check your application before resubmitting. If you’re unsure about the process, ETAPORTAL provides expert support to help with your application. Their guidance can make resubmission faster and more accurate.
