I left Korea while under investigation for drug trafficking and I've been abroad for three years — is there an Interpol notice on me, and does the case ever expire?

There is very likely a Korean arrest warrant in your name, issued after you failed to appear, and the case is very likely recorded as suspended with a flag against your entry. Whether there is an Interpol red notice is a separate question: Korea issues them selectively, mostly for trafficking-scale cases, and "a handful of deliveries" for a friend's channel is at the margin. Korea and the US have an extradition treaty covering drug offenses, and Korea does request extradition — but in practice it does so for significant traffickers, not for delivery helpers who left after one interview. The case does not expire on the timeline you might hope, because the limitation period is suspended while you are abroad to avoid prosecution. The least bad way back is to deal with the case before you set foot in Korea, from the US, through counsel.

What this is under Korean law

Assisting sales through a channel — deliveries — is charged as sale of a narcotic under Article 59 of the Narcotics Control Act (마약류관리법, mayangnyu gwalli-beop) or as aiding it, depending on your role; if the channel was organized, Article 114 of the Criminal Act (criminal organization) may have been added for the principals. A one-year minimum applies to sale; aiding is punished at a reduced range. You were "told to expect a warrant hearing," which means the prosecutor had applied or was applying for detention; leaving the country before it is a fact that would be treated as flight.

The warrant, the flag, and Interpol

After a suspect fails to appear, the police or prosecutor obtain an arrest warrant (체포영장, chepo yeongjang), the case is suspended (기소중지, giso jungji) as to you, and the Immigration Office enters a flag: on any arrival at a Korean port you would be detained on the warrant. That is certain enough to plan around.

A red notice is a request to other Interpol members to locate and provisionally arrest a person pending extradition; Korea requests them through its Interpol bureau for cases it intends to pursue internationally. Whether one exists for you can be checked: Interpol accepts requests from individuals to be told whether they are the subject of a notice, through its Commission for the Control of Files, and Korean counsel can inquire about the warrant and the case's status with the prosecutor's office directly. Both should be done before any travel.

Extradition and third countries

The US–Korea extradition treaty covers offenses punishable in both countries by more than a year's imprisonment, which drug sale is. Korea requests extradition from the US for cases it judges worth the cost — organizers, large quantities, fugitives from sentences. A delivery helper with a suspended investigation is not a typical request, and three years of silence suggests none has been made. That is a description of practice, not a promise.

In third countries, a red notice, if one exists, could lead to detention at a border and a Korean extradition request to that country; without a notice, third-country travel is unaffected by a Korean domestic warrant. This is why the notice check comes first.

Limitation

The limitation period for an Article 59 offense is ten years from the act under the Criminal Procedure Act's schedule — and under Article 253(3), the period is suspended for the time a suspect stays abroad for the purpose of avoiding prosecution. Your departure the week after the interview is the kind of fact that would be treated as avoidance. The clock has, in all likelihood, not been running. The case does not expire in the way you have been hoping.

The least bad way back

It is to resolve the case from the US. Korean counsel, under a power of attorney (위임장, wiimjang), confirms the warrant and the charge, opens contact with the prosecutor, and negotiates the terms of your return: typically a voluntary appearance on a fixed date, with the arrest warrant withdrawn or converted so that you are not taken into custody at the airport, and a case that proceeds without detention on the strength of your voluntary return. Prosecutors agree to that for suspects whose role was minor and whose return closes an open file; they do not agree to it for suspects who arrive unannounced. The alternative — arriving on a tourist visa and hoping — is detention at Incheon and a case that begins with flight as its first fact.

The likely disposition for a minor role, voluntary return and cooperation is a suspended sentence; the immigration consequence of any conviction is removal and a ban, decided by the Immigration Office. MEGA X handles the criminal case and the negotiation of return.

What to do now, and what not to do

Do not travel to Korea. Do not travel to countries with active extradition practice with Korea until the notice check is done. Have Korean counsel confirm the warrant and the charge, and file the Interpol inquiry. Assemble what you have from four years ago. Decide, with counsel, whether to negotiate a return now or to wait — understanding that waiting does not run the clock.

From a former police investigator's perspective

Suspects who leave mid-investigation are the files every unit has in a drawer: warrant issued, suspended, flagged, forgotten until the person lands. Investigators do not chase delivery helpers across oceans; they wait, and the immigration desk does the work when the suspect eventually visits a friend's wedding. A suspect who returns by arrangement, through a lawyer, is a file the prosecutor closes without drama; one who returns by surprise is a file that begins with handcuffs at the gate.
