Even if a person has no record of directly using drugs, cases continue to occur in which foreign nationals become subjects of investigation simply for being present at a drug-related scene. There have been many instances where individuals were indicted solely based on suspected possession or statements given as witnesses, even when their drug tests returned negative.
In particular, foreign nationals may face immigration control measures even before their criminal sentencing is determined. In practice, procedures such as visa cancellation or an order to depart can be reviewed first through separate administrative steps handled by immigration authorities.
The critical issue is that these actions can proceed regardless of whether the allegations are proven or whether the individual tests positive. If the initial response is insufficient, a foreign national’s stay in Korea may be terminated regardless of the outcome of the criminal trial.
Because foreign drug-related cases require simultaneous attention to both criminal defense and immigration procedures, it is extremely difficult to resolve such matters alone without expert guidance. Therefore, obtaining assistance from a legal representative who is well-versed in both areas is the safest course of action.

1. In drug-related cases involving foreign nationals, even first-time offenders can receive a prison sentence.
Even in cases involving simple possession or temporary use, it is difficult to assume that a foreign national will receive a light penalty when implicated in a drug-related incident. This is because cases continue to arise in which first-time offenders are not granted leniency.
The following circumstances may lead to a higher sentencing range for drug offenses:
- When drugs are discovered in a public place or during immigration inspection
- When the test result is positive or evidence of purchase is clear
- When the circumstances or frequency of use are specifically revealed, even if the amount is small
Not only the events leading up to the criminal charges but also surrounding factors—such as the place of arrest and the method of use—are taken into account. Even if the incident involves one-time possession, if voluntary possession or use is confirmed, many cases proceed to imprisonment rather than a deferred indictment.
In addition, for foreign nationals, immigration procedures begin separately from the criminal trial, and visa cancellation, forced departure, and re-entry bans occur far from rarely.
Ultimately, the more burdensome issue is that one’s life in Korea may come to an end—regardless of the criminal penalty itself.
2. If you are on trial for suspected drug possession, you need strategies to reduce the likelihood of imprisonment.
If you have already been indicted in a drug-related case as a foreign national and a trial is scheduled, it becomes crucial to begin preparing realistically to reduce the potential punishment.
The fact that the initial investigation stage has ended means that simple explanations or requests for leniency are no longer sufficient. At this point, you need to organize concrete materials that can influence the court’s sentencing decision.
For example, such materials may include:
- A factual explanation of how you came to possess the substance
- Details about the type and quantity of the drug, whether it was used, and how many times
- Documentation of prior criminal history or evidence demonstrating remorse
- Specific reasons you need to continue living in Korea and documents supporting your residency basis
These preparations cannot rely on vague statements alone. You need a comprehensive set of materials—sentencing documents, written statements, and legal counsel opinions—to increase the likelihood of outcomes such as a suspended sentence or a deferred judgment.
In some cases, it may be possible to argue for acquittal. However:
- If a positive drug test result already exists, or
- If possession is clearly evidenced,
then a sentencing mitigation strategy may be more realistic.
Additionally, immigration procedures may immediately follow the outcome of the criminal trial. Preparing without delay can help prevent not only imprisonment but also visa cancellation or forced deportation.
Delays in response after an indictment can increase the likelihood of imprisonment, so it is essential to establish a clear direction from the early stages.
3. Criminal penalties for foreign nationals may not end with a simple fine.
Receiving a fine in a drug-related case involving a foreign national does not mean the matter is fully resolved. If the fine exceeds 3 million won, the individual is categorized for an offender review, during which their residency status is re-evaluated. In other words, even if the criminal penalty is relatively light, immigration procedures may still proceed separately—and this must not be overlooked.
In many real cases, despite receiving a low sentencing range, foreign nationals have still faced visa cancellation or forced deportation. For foreigners, a fine is not treated as meaningful “leniency,” so it is necessary to prepare a defense even at this stage.
It is advisable to prepare the following materials in advance:
- A detailed explanation of the circumstances surrounding possession or use
- Documentation of treatment history or rehabilitation efforts following a positive test result
- Reasons why continued residence in Korea is necessary
- Evidence of family, employment, studies, or other ties that support your residency
These materials should not simply be lengthy; they must present facts and circumstances in a way that is objectively credible, and statements must be consistent with the submitted documents.
In addition, during the offender review, it is important to focus on the key issues, and attending the procedure with a legal representative can be significantly beneficial.
4. In many foreign drug cases, immigration and residency problems continue long after the criminal punishment is over.
As emphasized repeatedly, drug-related cases involving foreign nationals involve important procedures that continue even after the criminal trial has concluded.
Even if the court imposes a fine or a suspended sentence, immigration authorities will separately review the individual’s residency status, and in many cases, this review results in visa cancellation or deportation.
Therefore, responding only to the criminal trial is not enough to secure continued residence in Korea.
In actual cases, two areas of preparation are required simultaneously:
- Criminal defense strategies to reduce the sentencing range
- Immigration-response strategies to maintain residency
You must plan in advance not only the consistency of statements and documents, the content of your reflection letter, and the overall composition of sentencing materials, but also what documents to submit during the immigration procedures and how to present them. Only with such preparation can both the criminal penalty and residency issues be managed together.
