Your Lawyer in Korea

I’m Tae-moon Uhm, an English-speaking attorney helping foreigners navigate the complexities of the Korean legal system. From visa disputes to criminal defense, I’m here to ensure you never have to face the law alone.

If you have received a call or a text message from the Korean police regarding a narcotics investigation, your legal status in Korea is at a critical crossroads. In South Korea, drug offenses are treated with “zero tolerance,” and for foreigners, the consequences extend far beyond a fine—it almost always involves departure order.

Here is a strategic guide on how to handle a police summons for drug-related charges in Korea.

1. Do Not Ignore the Summons

Ignoring a police phone call or a formal summons (출석요구) is the worst first step.

  • The Risk: If you are uncooperative, the police may apply for an arrest warrant, citing you as a flight risk or a risk of destroying evidence.
  • The Action: Acknowledge the call politely, but do not provide details over the phone. State that you need to check your schedule and consult with legal counsel before setting a date.

2. Understand the “Foreigner Double Penalty”

In Korea, a criminal conviction for drugs usually triggers a secondary punishment from the Immigration Service:

  • Criminal Penalty: Prison time or heavy fines.
  • Administrative Penalty: Even a suspended sentence or a relatively small fine can lead to a Departure Order (출국명령) or Forced Eviction (강제퇴거).

3. Preparation Before the First Investigation

The first interrogation is the most important. What you say is recorded in a “Record of interrogation of a suspect” (피의자 신문조서), which becomes the primary evidence in court.

Hair and Urine Tests

Expect to undergo drug testing immediately upon arrival.

  • Urine tests detect recent use (usually within 3–7 days).
  • Hair samples can detect drug use from months ago.
  • Note: Attempting to bleach your hair or shave your body to avoid testing is often viewed by Korean courts as an admission of guilt and an attempt to destroy evidence.

Secure a Professional Interpreter

While the police will provide an interpreter, they are often not legal experts. There may be nuances lost in translation that could imply “intent” where there was none. You have the right to request a high-quality interpretation or bring a lawyer who is fluent in both languages.

4. Exercise Your Right to Legal Counsel

In South Korea, you have the right to have a lawyer present during questioning.

  • Why? A lawyer can interrupt if the questioning becomes coercive and can help you clarify statements that might be misinterpreted as a confession of “distribution” (selling) vs. “simple possession.”
  • The Goal: To minimize the charge. In drug cases, the difference between “Intent to Distribute” and “Self-Consumption” is the difference between years in prison and a potential stay in Korea.

5. Summary Checklist for Your First Visit

Action ItemWhy it Matters
Check the ChargeAsk exactly which drug and which act (use, sale, or possession) you are suspected of.
Remain CalmAggressive behavior toward Korean officers is often viewed as a lack of remorse (반성).
Review the ProtocolBefore signing the interrogation transcript, read it carefully. If it’s wrong, demand a correction.
Consult a LawyerIdeally, speak to a lawyer before your first step into the station.

Conclusion: Act Fast to Protect Your Visa

A drug investigation in Korea is not just a legal battle; it is a battle for your right to stay in the country. If you are summoned, the “wait and see” approach is dangerous.
