Police searched my apartment and found three cannabis plants I was growing for myself — I'm on an E-7. Is cultivation treated like dealing in Korea?

Cultivation is not treated like use in Korea; it sits in the same statutory category as manufacture and trafficking, and the range starts where a user's ends. That is what "very serious" meant, and it is accurate. What the sites you read do not say is how cultivation cases for a few plants, for personal use, with no evidence of supply, are actually resolved — which is with a suspended sentence far more often than with prison, provided the file stays a personal-use file. Detention is a real risk at the warrant stage for this offense; the phone and laptop are what decide whether the file stays personal. You need counsel before the summons, not at trial.

What this is under Korean law

Under Article 59 of the Narcotics Control Act (마약류관리법, mayangnyu gwalli-beop), cultivating cannabis is punishable by imprisonment of one year or more — the same provision that covers manufacture, import, export and trafficking. There is no fine option and no separate "personal-use cultivation" tier. Three plants is a small cultivation, and courts recognize the difference between a closet and a farm in sentencing, but the offense is the offense. Possession and use of what you grew are charged alongside under Article 61.

Because the statutory minimum is one year, a court that wants to avoid prison for a first offender must find mitigating circumstances to reduce below the minimum and then suspend; that is the shape of a good outcome, and it is a shape Korean courts have used for personal-use growers with no supply, clean records and cooperation. It is not automatic.

Detention

The police released you after questioning, which means they did not seek a warrant on the day; that is a good sign, not a guarantee. When the case is referred, the prosecutor may still seek detention for a cultivation offense — flight risk, for a foreign national, is the argument — and the answer is the same as in every foreign-national case: a fixed address, three years' employment, a passport surrendered if needed, counsel on record, and a file that shows personal use. Prepare for a warrant hearing (영장실질심사, yeongjang siljil simsa) as if it will happen.

The phone and laptop

Investigators are looking for two things: supply — messages offering, selling or sharing; and scale — seed orders, grow-forum posts, photos of the plants over time, contacts. A grower who bought seeds once and never messaged anyone about the plants has a file that stays personal. A grower with a message saying "I'll bring some" to a friend has a supply file, and the range changes. You are entitled to be notified of and present at the forensic examination; counsel asserts that right and limits the scope to the offense. Do not attempt to access or wipe cloud backups; that is obstruction and it is visible.

Your situation as a foreign national

A departure suspension (출국정지, chulguk jeongji) should be assumed. You are entitled to an interpreter and counsel at every stage.

A conviction under Article 59, even suspended, is squarely within the grounds the Immigration Office reviews for deportation; drug offenses are among the categories it treats most seriously, and cultivation more so than use. That review is discretionary, decided by the Immigration Office on the offense and your circumstances, and we do not predict it — but you should understand that the immigration consequence of a cultivation conviction is more likely than for use, and that the sentence's shape and reasoning feed directly into that review. Your employer is not notified by the police; a status consequence would involve them later. MEGA X handles the criminal case; where it affects your status, we coordinate with an immigration specialist as part of your defense.

What to do now, and what not to do

Retain counsel before the summons. Do not discuss the case with anyone who might be in your messages. Enroll in a treatment or education program now and keep the record. Gather your employment contract, lease and tax records for the detention question. Prepare your account with your lawyer: what you grew, why, for how long, and that nothing left the apartment.

From a former police investigator's perspective

Cultivation searches are triggered by a seed order intercepted at customs or a tip, and the investigator arrives knowing the statute is severe and wanting to know only one thing from the devices: did any of it leave the closet. A grower who says so, whose phone confirms it, and who has already started a program is a file that the prosecutor can refer without a detention request. A grower whose phone shows a single "want some?" is a different file, and no amount of remorse changes it.
