South KoreaI was denied entry at the airport.
You may be denied entry to South Korea if you lack proper documentation, pose a security risk, or fall under statutory inadmissibility grounds under the Immigration Act.
What the Law Says
South Korean immigration authorities may refuse entry at ports of entry—including airports—based on clear statutory grounds. The Immigration Act sets out who is ineligible to enter and empowers officials to deny entry on those bases.
Under Article 11(1) of the Immigration Act, a foreign national may be denied entry if they fall into any of several categories — including lacking a valid passport or visa, failing to meet health or security requirements, having been previously deported, or providing false information.
Article 12 explicitly authorizes immigration officers at ports of entry (e.g., Incheon Airport) to refuse entry to any foreign national who meets the inadmissibility criteria in Article 11(1). This decision is made on the spot and does not require a court order.
If entry is refused, the person must either depart immediately or remain in the designated transit area for up to 72 hours while arrangements are made — unless detained under Article 14 for investigation. Providing false or forged documents can lead to a fine of up to KRW 20 million or imprisonment, per Article 93(1)(i).
A person denied entry due to fraud or misrepresentation may be barred from re-entering South Korea for up to five years under Article 11(3).
Statutory TextA foreign national falling under any of the following subparagraphs shall not be permitted to enter the Republic of Korea: (i) One who does not possess a valid passport or travel document; (ii) One who fails to satisfy the conditions required for entry… (vii) One who has submitted false information or forged documents…
— Immigration Act, Art. 11(1)

What to Do
Ask the immigration officer for the specific reason and legal basis (e.g., Art. 11(1)(vii)) for denial.
Request written confirmation of the refusal and retain all related documents.
Contact your country’s embassy or consulate in South Korea for consular assistance.
If eligible, apply for a new visa or correction of records before reapplying for entry.
Consult a licensed Korean immigration attorney to assess appeal options or re-entry eligibility.
