Many foreign clients experience panic, fear, and confusion when working with Vietnamese investigative authorities. Some believe that because they are foreigners, they will be “handled under their home country’s law” or “fully protected by their embassy or consulate.” However, Vietnamese criminal law has very clear provisions, along with several important exceptions. If these are misunderstood, foreign nationals may make unfavorable decisions from the very beginning.

General principle: acts committed in Vietnam are subject to Vietnamese law

Pursuant to Article 5 of the 2015 Criminal Code (as amended and supplemented in 2017), the basic principle is:

Any foreign national who commits a crime within the territory of the Socialist Republic of Vietnam shall be handled in accordance with the Vietnamese Criminal Code.

In simpler terms:
If the alleged criminal act occurs in Vietnam, regardless of nationality, Vietnamese law has jurisdiction to handle the case.

This principle applies to:

  • Foreign nationals residing, working, or traveling in Vietnam

  • Foreign nationals transiting through Vietnam who commit criminal acts

  • Foreign nationals involved in or related to criminal cases occurring in Vietnam

However, this is not the whole picture.

Are there cases where foreign nationals are not handled under Vietnamese law?

Not all cases involving foreign nationals in criminal matters in Vietnam are handled in exactly the same way. Vietnamese law provides certain exceptions, mainly related to diplomatic immunity and international treaties. These situations are relatively rare and are often misunderstood as meaning “no criminal liability.” Understanding the actual scope of these exceptions helps avoid unrealistic expectations and enables an appropriate legal strategy from the outset.

Important exception: diplomatic immunity

Vietnamese criminal law is not applied in the usual manner to individuals who enjoy diplomatic or consular immunity, such as:

  • Diplomatic staff

  • Consular officers

  • Certain officials of international organizations

In such cases, handling is conducted through:

  • Diplomatic channels

  • International treaties to which Vietnam is a party

  • Agreements between Vietnam and the relevant foreign state

However, the vast majority of foreign nationals living and working in Vietnam do not fall into this category.

What about bilateral treaties?

Vietnam has entered into many mutual legal assistance treaties with other countries. These treaties may affect:

  • Extradition

  • Enforcement of criminal judgments

  • Transfer of sentenced persons

It should be noted that:
A treaty does not mean “no prosecution.” It only regulates the manner and scope of handling, not the complete exclusion of criminal liability.

What do foreign nationals usually fear when under criminal investigation in Vietnam?

Foreign nationals commonly have the following concerns:

Fear of prolonged detention without understanding the reason
Many are unfamiliar with Vietnamese criminal procedures and do not understand:

  • Why they are being detained

  • How long detention may last

  • Whether bail or release pending investigation is possible

Fear of language barriers leading to misunderstandings or improper signatures
Working without a qualified legal interpreter may result in:

  • Misunderstanding investigators’ questions

  • Making unfavorable statements

  • Signing records that do not reflect their true intent

Fear of harsher treatment because they are foreigners
This is a common concern, but in practice:
Vietnamese law does not impose harsher penalties solely because a person is a foreign national.

Criminal liability depends on:

  • The specific conduct

  • Degree of fault

  • Consequences of the act

  • Aggravating and mitigating circumstances

What rights do foreign nationals have during criminal investigations in Vietnam?

Even as a foreign national, you have important procedural rights, including:

The right to legal counsel
You have the right to:

  • Engage a Vietnamese lawyer from the investigation stage

  • Have a lawyer protect your rights and manage legal risks

This is a critical right, yet often overlooked at the early stage.

The right to an interpreter
Procedural authorities are obligated to:

  • Arrange an interpreter during proceedings

  • Ensure you fully understand questions, answers, and written records

The right to consular notification
Under the Vienna Convention, foreign nationals who are arrested or detained have the right to:

  • Request notification to their embassy or consulate

However, it is important to understand that:
An embassy or consulate does not replace a lawyer and does not directly intervene in the substance of a criminal case.

The role of lawyers in cases involving foreign nationals in Vietnam

In cases with foreign elements, lawyers are not only defense counsel, but also professionals who:

  • Explain the Vietnamese legal system in an accessible manner

  • Work professionally with investigative authorities

  • Minimize risks arising from cultural and legal differences

At DEDICA Law, we often become involved at an early stage to:

  • Assess actual criminal risks (without speculation or intimidation)

  • Develop appropriate legal strategies for each stage of the case

  • Protect clients’ lawful rights and interests to the greatest extent possible

Professional disclaimer:
Each case has its own characteristics. The assessment of criminal liability depends on case files, evidence, and procedural developments. This article is for reference only and does not constitute a guarantee of case outcomes.

When should foreign nationals seek a lawyer immediately?

You should not wait until formal prosecution or arrest. Seek legal assistance immediately if you:

  • Receive an invitation to work with the police

  • Are detained or held in custody

  • Show signs of being under criminal investigation

  • Are a victim in a criminal case involving foreign elements

Decisions made at the early stage can affect the entire case later.
