Foreign National Involved in Voice Phishing Fraud: How to Protect Your Stay from Police Investigation to Sentence Reduction?

  Were you criminally charged for aiding a voice phishing scam even though it was “just a part-time job”?   Or have you been mistakenly suspected as an accomplice and notified of an upcoming police investigation?   In voice phishing cases involving foreign nationals, early response is extremely important. Depending on how the case is handled at the outset, not only the possibility of sentence reduction, but also visa extension and the ability to maintain legal stay can be affected.   Recently, as voice phishing schemes targeting foreigners—such as romance scams or cryptocurrency investment fraud—have increased, investigative authorities have adopted a much stricter stance, thoroughly investigating even those who were only minimally involved.   If you let your guard down because you believe you are innocent, the case can escalate to actual imprisonment, and even a fine may result in disadvantages during immigration review.   Situations where police investigations and criminal charges proceed simultaneously are difficult to handle alone. To pursue both sentence mitigation and stable residency, it is safest to seek assistance from a legal professional experienced in both criminal defense and immigration matters.

1. Voice phishing fraud: how severe is the actual punishment?

  When a foreign national is criminally charged in a voice phishing case, the most immediate concern is usually the level of punishment.   Voice phishing constitutes fraud, which carries a statutory penalty of up to 10 years’ imprisonment or a fine of up to 20 million KRW. However, the actual sentence is not determined solely by the wording of the law.   The severity of punishment varies depending on factors such as whether the individual lent a bank account only once, repeatedly acted as a cash withdrawal courier, the scale of the financial damage, and whether the person was aware of the criminal nature of the activity. Even if it was “just a part-time job,” imprisonment may be imposed if investigators view the case as part of an organized crime.   For foreign nationals in particular, the outcome of the criminal case is directly linked to visa extensions and immigration status reviews, making it necessary to consider immigration consequences alongside sentence reduction.   At the early stage of the case, clearly organizing and documenting your level of awareness and your role in the offense can make a significant difference in later legal judgments that affect your right to remain in the country.    

2. “It was just a part-time job…” What if you’re investigated by the police for voice phishing?

  An increasing number of cases involve foreign nationals becoming entangled in voice phishing investigations after participating in what they believed to be simple part-time work, introduced through acquaintances or social media.   Even if a person only withdrew cash or delivered money, investigative authorities may view this as participation in a fraud scheme and proceed with an investigation under accomplice charges. At that stage, explanations such as “I only did what I was told” are often insufficient to avoid responsibility. Even without understanding the full structure of the crime, contributing to the outcome can still result in criminal liability.   That said, not all cash couriers are punished equally. Sentencing may vary depending on:
  • Whether the person recognized the criminal nature of the act
  • The level of voluntariness
  • The scale of financial damage
  • Whether the conduct was repeated
  During the police investigation stage, it is crucial to clearly explain your personal circumstances and the course of your actions, and to persuasively convey that you participated without knowing it was a fraud scheme.   When efforts such as victim compensation or criminal deposits (공탁) are made to demonstrate responsibility, there is a real possibility that the case may conclude with a fine or a suspended judgment, rather than imprisonment. Even when roles are similar, the outcome can differ entirely depending on how statements are made and what is proven.   If your goal is to pursue sentence reduction while also maintaining your legal stay, clearly setting the direction of your response from the very beginning is essential.    

3. At the police investigation stage: what are the key response points for sentence reduction?

  In voice phishing cases involving foreign nationals, the actual sentence is not determined solely by whether one participated in the crime. Multiple factors are considered together, including how the person became involved, what role they played, and the scale of the financial damage and efforts made toward recovery.   In particular, the police investigation is the first stage where investigators formally record the suspect’s attitude and statements, and how one responds at this stage can have a significant impact on sentence reduction and the eventual trial outcome.   At this point, it is essential to prepare the following two elements:   Point 01 Establishing a favorable statement strategy Simply saying “I didn’t know” is not enough. You must clearly organize the circumstances at the time and the process by which you became involved, and present your position logically and consistently.   Point 02 Demonstrating willingness to recover damages If reaching a settlement with the victim is difficult, showing responsibility through criminal deposits (공탁) can still demonstrate an effort to reduce harm. Such actions can provide real, practical benefits in lowering the sentence.   If the direction is set correctly during the initial police investigation, it may be possible to establish yourself as a minor participant, avoid imprisonment, and conclude the case with a fine or a suspended judgment.   Voice phishing cases involving foreign nationals can lead to very different outcomes depending on the response strategy, and require an approach that considers immigration status issues alongside the criminal process.    

4. Why is it necessary to respond with visa issues in mind as well?

  When a foreign national is criminally charged in a voice phishing case and receives either a fine or a prison sentence, the consequences do not end with criminal punishment alone. Disadvantages may also arise during visa extension or immigration status reviews.   In Korea, there is a procedure called “criminal/immigration status review (사범심사)”, through which immigration authorities determine whether a visa can be renewed based on a foreigner’s criminal record and the nature of the offense. If the sentence is severe or if no settlement is reached with the victim, many cases result in denial of visa extension, forced departure, or even re-entry bans.   For this reason, responding only to the police investigation or criminal trial is not sufficient. From the outset, it is necessary to prepare a response that also takes immigration status issues into account.   For an effective strategy, the following three points are crucial:
  • At the police investigation stage, accurately explain the facts and cooperate with damage recovery efforts
  • During the criminal trial, emphasize mitigating factors favorable to sentencing—such as being a first-time offender or minor involvement—to seek sentence reduction
  • At the immigration review stage, clearly demonstrate your purpose of stay and established life base in Korea
  By addressing visa issues alongside the criminal case from the very beginning, it is possible to increase the likelihood of maintaining lawful residence in Korea even after a voice phishing case involving a foreign national.    

5. More frightening than criminal punishment is losing your right to stay.

  When a foreign national is criminally charged in a voice phishing case, it is not simply a matter of paying a fine and moving on. Once the sentence is finalized, visa renewal may be denied or stay extensions may be discontinued. Depending on the circumstances, many cases even lead to departure orders or forced deportation.   For foreign nationals who have already established a stable life in Korea, such measures can be more devastating than imprisonment itself.   For this reason, from the very beginning of the case, it is essential to adopt a strategy that considers police investigations, criminal trials, sentence mitigation, and the ability to remain in Korea all at once.   We have extensive hands-on experience handling numerous criminal cases involving foreign nationals and voice phishing, and we provide practical support from the initial statements through the immigration review stage.   If you wish to protect your right to stay in Korea, establishing a clear legal response strategy at this moment is the most realistic and effective choice.     Multilingual consultation available in English and Chinese.   Professional interpreters assist from the first consultation to the conclusion of the case.   Offices in Seoul, Daejeon, Busan, Daegu, and Gwangju   Don’t face the legal system alone.
