I failed K-ETA, can I re-register?

If you do not pass K-ETA, you must wait at least 1 week to 1 month to reapply.
If you submit the same application three times within six months, you can reapply six months from the date of your initial application.
Please apply closer to the actual entry date (within 1 to 2 months from the scheduled entry date) rather than a few months in advance.
Applicants must submit only factual information or they may be subject to penalties.
