Foreign Fraud & Voice Phishing Cases — Key Defense Points You Must Not Miss During Police Investigation After Arrest

 

“I only did someone a favor — why am I being investigated?”

  This is how most cases begin when foreigners become involved in voice phishing or fraud incidents in Korea.   What may have started as a simple act of kindness — such as lending a bank account or delivering cash — can later be connected to a criminal scheme, leading to a police investigation for fraud charges against the foreign national.   Moreover, if the person is not fluent in Korean or lacks understanding of the investigative procedures, they often struggle to explain their situation properly, which can place them at a disadvantage.   Most importantly, merely saying “I was just helping someone” is not enough to prove innocence. In such cases, it is crucial to seek assistance from a legal representative and prepare a thorough defense strategy from the very beginning of the investigation.

1. Voice Phishing Involvement — How Far Can Criminal Penalties and Immigration Consequences Go?

  When a foreigner is investigated for voice phishing, the charge is usually fraud (사기죄), which carries a maximum sentence of 10 years in prison or a fine of up to 20 million KRW.   However, even if the individual only allowed the use of their bank account or was involved in receiving cash, the situation changes if similar transactions were repeated or if there were multiple victims. In such cases, the Act on the Aggravated Punishment of Specific Economic Crimes may apply, leading to heavier penalties.   In particular, many foreigners who accept short-term job or remittance offers unknowingly become classified as “money mules” and end up receiving prison sentences. If their statements during the police investigation are unclear, their limited involvement can easily be interpreted as active participation in the crime.   The greater problem arises after conviction. Once a foreigner receives a sentence of imprisonment or higher, they become subject to a disciplinary review under the Immigration Control Act, which can result in visa renewal denial or even deportation.   Foreign-related fraud cases are not merely about criminal defense — they are directly linked to immigration status. The most effective approach is to seek help from a legal professional early on, preparing simultaneously for both the criminal investigation and the potential immigration consequences to ensure a stable and comprehensive resolution.    

2. What Should You Prepare for During Police Investigation or Arrest?

  Most foreign fraud cases begin with a police investigation, and the statements made during this stage can heavily influence the direction of the case.   If there are suspicions of involvement in voice phishing, it is crucial to prepare objective supporting materials that clearly explain your actions in advance.   During the early investigation stage, you should organize the following details clearly:

• A chronological record of how and with whom each transaction took place
• The source and purpose of any money transferred or items delivered, and your relationship with the other party
• Bank transaction records showing that there were no repeated or suspicious deposits and withdrawals
• Text messages, chat logs, or other communications showing that you were simply following instructions or requests

  If you are under arrest, it is essential to consult with a legal representative before making any statements and to ensure that interpretation during questioning is accurate. Inaccurate translation or miscommunication of your intent can result in your statements being misunderstood as evidence of guilt.   It is also important to remember that responding only to the criminal investigation does not end the matter.   Foreign voice phishing cases often extend to immigration review, and inconsistencies between your criminal defense statements and immigration documents can lead to disadvantages. Therefore, a coordinated and integrated legal strategy is necessary — one that addresses both the criminal investigation and the immigration implications simultaneously.    

3. Case Study: How a Foreign Student Responded to Voice Phishing Allegations

  A, a British international student in Korea, was running a small online purchasing business alongside his studies when he received a currency exchange request through an online community.   Without much suspicion, he allowed the requester to temporarily use his bank account. However, within a few days, the account was identified as part of a voice phishing money transfer route, and A was summoned for a police investigation.   Initially, he thought it was just a personal transaction, but investigators cited repeated transfers and victim statements as grounds to suspect A of being an accomplice in a foreign fraud case. His bank account was immediately frozen, and a travel ban was issued.   As the situation escalated rapidly, A sought help from a legal representative. The attorney submitted accounting records explaining the background of the exchange, the purpose of the account use, and the actual profit structure, demonstrating that A had not participated in the phishing scheme but had been unknowingly exploited as a victim.   As a result, A received a non-indictment decision (no charges filed) in the criminal case, and in the subsequent civil lawsuit, the court found no intent to commit wrongdoing and dismissed all claims.   This case illustrates that in foreign fraud investigations, mere verbal statements are rarely enough to prove innocence. Substantive legal defense is only possible when professional legal support is involved from the earliest stage of the investigation.    

4. Foreign Fraud Cases Require Both Criminal Defense and Immigration Protection to Be Prepared Together.

  Foreign fraud cases linked to voice phishing may appear to involve ordinary transactions on the surface, but even actions such as allowing the use of a bank account or delivering cash can be interpreted as participation in an organized criminal scheme.   After arrest, investigations often become prolonged, and the results of the police inquiry can have a direct impact on visa renewal and residency status.   In situations where criminal proceedings and immigration reviews are intertwined, focusing solely on the investigation or addressing only the immigration issue can easily cause you to miss the bigger picture.   In fact, statements made during the police investigation are often reflected in immigration records, which is why it’s essential to have a comprehensive, coordinated strategy from the very beginning that takes into account the entire process — from criminal defense to immigration management.
