Even a single remittance can raise suspicion of illegal currency exchange.
If you allowed someone to use your bank account at their request to send money on their behalf, or if you transferred cash locally without using a formal financial channel, you may become subject to an investigation for violation of the Foreign Exchange Transactions Act.
In particular, even when the amount involved is not large, if the method of transfer is deemed abnormal, the case may lead to criminal penalties and restrictions on residency status. Even acts intended as simple favors can be classified as illegal transaction if the flow of funds cannot be clearly explained.
In actual cases, the key issues are whose money it was and why that particular transfer route was used. For this reason, there are clear limits to handling explanations on your own at the early stage.
If you want to respond properly to an investigation for violation of the Foreign Exchange Transactions Act, it is safest to seek assistance from a legal professional from the very beginning.

1. Violations of the Foreign Exchange Transactions Act Can Arise Closer Than You Expect
When foreign currency is sent or received overseas, the transaction may be deemed a violation of the Foreign Exchange Transactions Act if the remittance structure or method appears abnormal. Even a simple transfer can immediately become suspicious if non-bank channels are used or if the flow of funds is unclear.
- Receiving foreign currency on behalf of an acquaintance,
- making a detoured transfer through a third party, or
- sending money using an account in someone else’s name
can all be sufficient to raise suspicion of illegal currency exchange. Even when the amount involved is small, if the method of transfer appears structurally irregular, the possibility of punishment remains.
Investigative authorities focus less on the amount and more on why that route was chosen, whether the conduct was repeated, and whether the transfer can be proven to be for personal use. If supporting explanations or documentation are insufficient, even acts of simple assistance may be reclassified as illegal transaction-related offenses, leading to criminal penalties.
Because remittances that normally seem routine can, under certain circumstances, be recharacterized as criminal conduct, it is far safer to organize and document the relevant transaction history in advance.
2. Once Illegal Currency Exchange Is Suspected, the Investigation Begins Quickly
Illegal transactions often operate by receiving Korean won domestically and delivering foreign currency overseas. When third-party accounts or cash-based handovers are involved in this process, an investigation for violation of the Foreign Exchange Transactions Act may be initiated.
Even if an individual claims that they were merely complying with a request, the investigation will not stop if the remittance route and method are judged to fit an illegal currency exchange structure. The involvement of third-party transfer flows or the direct handover of foreign currency abroad alone can be sufficient to establish illegality.
- Legally, transferring foreign currency without proper reporting may result in penalties of up to one year of imprisonment or a fine of up to 100 million KRW.
- If illegal transaction-related charges are added, the level of punishment may increase to up to three years of imprisonment or a fine of up to 300 million KRW.
Recently, indirect transfers using virtual assets (cryptocurrency) have also been included as targets of investigation.
In particular, foreign nationals cannot assume the matter is resolved even after a criminal case concludes. Even a suspension of indictment or a fine may lead to cancellation of residency status or deportation measures at the immigration review stage.
For this reason, it is essential to prepare not only for the criminal investigation itself, but also to organize materials that clearly explain the purpose of the remittance and the flow of funds.
3. Even If the Case Ends With a Fine, Residency Issues May Follow
Even when a case involving a violation of the Foreign Exchange Transactions Act is concluded with a fine or a suspended sentence, foreign nationals face an additional issue. Separate from the criminal process, immigration authorities conduct a renewed residency review.
The Immigration Office examines not only the criminal record, but also the method of remittance and the flow of funds, and reviews whether to deny visa renewal or order deportation based on criteria such as:
- a fine of 3 million KRW or more,
- cumulative fines exceeding 5 million KRW within the past five years, or
- a sentence of imprisonment or a suspended sentence.
In particular, once a departure order is issued, future entry into Korea may be restricted, making it essential to prepare a strategy that addresses both immigration consequences and criminal defense from the very beginning of the case.
4. To Avoid Penalties, Proof Comes First
Even when there is suspicion of a violation of the Foreign Exchange Transactions Act, not every case automatically leads to criminal punishment. When the initial response is well organized, many cases are resolved relatively lightly, such as through a suspension of indictment or a fine.
If the following conditions are established, investigative authorities may regard them as mitigating factors:
- The transaction occurred only once, showing no pattern of repetition, and the amount involved was not significant
- The purpose of the remittance was clearly for personal use, such as medical or educational expenses
- There was no identifiable victim and a lack of clear criminal intent
- The individual acknowledged the facts during the investigation and voluntarily returned the funds
These circumstances are difficult to explain through statements alone and must be supported by objective evidence, such as remittance records, message histories, and documented fund-flow summaries.
Effectively demonstrating (1) that the incident was a simple mistake, and (2) that it was clearly distinct from an illegal transaction structure, is the key strategic approach to reducing or avoiding penalties.
5. Illegal Currency Exchange Allegations: The Right Strategic Direction Changes the Outcome
As mentioned earlier, even when a transfer appears to be a simple remittance, a suspected violation of the Foreign Exchange Transactions Act may be interpreted as illegal hawala if the method of fund delivery or account usage is unclear, potentially leading to criminal penalties.
For foreign nationals in particular, separate administrative procedures—such as denial of visa renewal, revocation of residency status, or deportation—may be initiated regardless of the outcome of the criminal investigation.
To avoid punishment or reduce its severity, it is essential to clearly organize the flow of funds and the purpose of the remittance from the outset, and to prepare both explanatory statements and supporting evidence. Establishing a clear response strategy before the investigation stage is the most practical way to influence the overall outcome.
In cases like these, we provide step-by-step support by:
- analyzing the remittance route and the purpose of fund usage,
- organizing the necessary explanatory and evidentiary materials,
- assisting with the preparation of a sincere written statement of apology, and
- preparing documentation to address immigration-related issues.
If your situation requires a strategic approach that considers both criminal proceedings and residency status, we recommend first reviewing what needs to be organized at this stage and how best to proceed.
