Vietnam';s immigration framework is detailed, frequently updated and enforced with growing rigour - making qualified legal counsel in Hanoi not a luxury but a practical necessity for foreign nationals and their employers. An immigration lawyer in Hanoi advises on the full spectrum of entry authorisations, work permits, temporary residence cards and corporate sponsorship obligations under Vietnamese law. This article maps the legal landscape, identifies the most common procedural traps and explains when and how to engage specialist legal support to protect your status and business operations in Vietnam.
Vietnam';s primary immigration legislation is the Law on Entry, Exit, Transit and Residence of Foreigners in Vietnam (Law No. 47/2014/QH13, as amended by Law No. 51/2019/QH14). This statute establishes the categories of visa, the grounds for refusal, the conditions for temporary residence and the penalties for non-compliance. Alongside it, the Labour Code (Law No. 45/2019/QH14) and Decree No. 152/2020/ND-CP govern the issuance and renewal of work permits for foreign employees.
The competent authorities in Hanoi are the Immigration Department under the Ministry of Public Security, which handles visas and temporary residence cards, and the Department of Labour, Invalids and Social Affairs of Hanoi (DOLISA Hanoi), which processes work permit applications. For corporate matters involving foreign-invested enterprises, the Hanoi Department of Planning and Investment also plays a role in confirming the legal basis for sponsoring foreign workers.
A non-obvious risk for many international clients is the assumption that Vietnamese immigration rules operate similarly to those in common-law jurisdictions. In practice, the system is administrative and document-intensive: approvals depend on precise form compliance, notarised translations and sequential submissions to multiple agencies. A single missing document can reset the entire timeline, which typically runs 15 to 30 working days for a work permit and 5 to 10 working days for a temporary residence card once all prerequisites are met.
The Law on Entry, Exit, Transit and Residence also introduced the e-visa system under Article 17a, allowing nationals of eligible countries to obtain a single-entry or multiple-entry e-visa valid for up to 90 days. However, the e-visa is not a substitute for a work permit or a temporary residence card, and using it for employment purposes constitutes a violation with administrative and potential criminal consequences under Article 17 of Decree No. 167/2013/ND-CP.
Vietnam issues visas across more than 20 categories, each designated by a letter code. The most commercially relevant for foreign professionals and investors are:
A common mistake made by international clients is entering Vietnam on a tourist visa (DL) and beginning employment or business activities before obtaining the correct authorisation. Vietnamese authorities treat this as an immigration violation, and the consequences include administrative fines, forced departure and a re-entry ban of up to three years under Article 21 of Law No. 47/2014/QH13.
The DN and LV visa categories require a sponsoring entity registered in Vietnam. The sponsor - typically the employer or a representative office - must file an invitation letter with the Immigration Department before the foreign national applies for the visa. This pre-approval step is often overlooked by companies setting up operations quickly, creating a gap during which key personnel cannot legally work.
For investors, the DT visa requires evidence of a registered investment project or capital contribution meeting the thresholds set by Decree No. 31/2021/ND-CP. The minimum qualifying investment is generally in the range of several hundred million Vietnamese dong, though the precise figure depends on the sector and project type. An immigration lawyer in Hanoi can assess whether a proposed investment structure qualifies and advise on restructuring if it does not.

A work permit (giấy phép lao động) is mandatory for most foreign nationals employed in Vietnam. Decree No. 152/2020/ND-CP, as amended by Decree No. 70/2023/ND-CP, sets out the eligibility criteria, the application procedure and the list of exemptions.
To qualify for a work permit, a foreign employee must generally satisfy the following conditions:
The employer must demonstrate that the position cannot be filled by a Vietnamese national. This requirement - known as the labour market test - involves publishing a job vacancy notice and obtaining confirmation from DOLISA Hanoi that no suitable local candidate is available. In practice, this step adds two to four weeks to the overall timeline and is frequently underestimated by foreign companies in a hurry to deploy staff.
Work permits are issued for a maximum of two years and are renewable. The renewal application must be submitted at least 45 days before expiry. Failure to renew on time results in the permit lapsing, which means the employee is technically working without authorisation - an outcome that exposes both the individual and the employer to administrative sanctions under Decree No. 28/2020/ND-CP.
Certain categories of foreign nationals are exempt from the work permit requirement. These include internal transferees within a multinational group (subject to conditions under Decree No. 152/2020/ND-CP, Article 7), individuals holding a DT investor visa with a qualifying capital contribution, and foreign lawyers registered with the Vietnam Bar Federation under the Law on Lawyers (Law No. 65/2006/QH11, as amended). Each exemption has specific documentary requirements, and relying on an exemption without proper documentation is a significant risk.
A practical scenario: a European technology company seconds a senior engineer to its Hanoi subsidiary for a software implementation project expected to last 18 months. The company assumes the internal transfer exemption applies automatically. In fact, the exemption requires a written confirmation from DOLISA Hanoi and a valid intra-company transfer letter meeting specific content requirements. Without these, the engineer is working illegally from day one, and the company faces fines and reputational exposure during any labour inspection.
A temporary residence card (thẻ tạm trú) replaces the need for a visa stamp and allows a foreign national to reside in Vietnam for a defined period - typically one to three years - without repeated visa renewals. It is the most practical long-term status for expatriate employees and their dependants.
The application is filed with the Immigration Department in Hanoi and requires, among other documents, a valid work permit, a sponsorship letter from the employer, proof of accommodation and a health certificate. Processing takes approximately 5 to 10 working days once the file is complete. The card is renewable and its validity is generally tied to the remaining validity of the work permit.
Dependants - spouses and minor children - can obtain temporary residence cards linked to the primary holder';s status. This is processed under the NN category for family members and requires certified translations of marriage and birth certificates, apostilled or legalised as appropriate for the country of origin.
A non-obvious risk arises when the primary holder';s work permit is not renewed in time. The dependants'; cards are administratively linked to the sponsor';s status, and a lapse in the work permit can trigger a cascade of compliance issues for the entire family unit. Many international clients discover this connection only after the problem has already materialised.
For senior executives and board members of foreign-invested enterprises, an alternative route exists through the DT investor visa and a corresponding temporary residence card, bypassing the work permit requirement entirely. This route is faster and carries fewer documentary burdens, but it requires the individual to hold a genuine equity stake or capital contribution in the Vietnamese entity. Structuring this correctly from the outset - rather than retrofitting it later - is considerably more efficient and less costly.

Vietnamese immigration enforcement has intensified in recent years. Labour inspections by DOLISA Hanoi and immigration checks by the Ministry of Public Security are conducted with greater frequency, particularly in industrial zones, technology parks and the hospitality sector. Foreign nationals found working without a valid work permit or on an incorrect visa category face administrative fines, deportation and re-entry bans. Employers face separate fines under Decree No. 28/2020/ND-CP, which can reach into the tens of millions of Vietnamese dong per violation.
A common mistake among international businesses is treating immigration compliance as a one-time task rather than an ongoing obligation. Work permits and temporary residence cards have fixed validity periods, and the renewal calendar must be actively managed. A company with 10 expatriate employees may have renewals falling due at different times throughout the year, each requiring a separate set of documents and agency submissions.
The risk of inaction is concrete: if a work permit expires and the employee continues working, every day of non-compliance adds to the potential fine exposure. DOLISA Hanoi has the authority to conduct unannounced inspections, and the burden of proof falls on the employer to demonstrate that all foreign staff are properly authorised.
Another strategic mistake is failing to account for the interaction between corporate structure and immigration eligibility. When a foreign-invested enterprise changes its legal form, adds new business lines or undergoes a shareholding change, the existing work permit sponsorships may need to be updated or reissued. The Immigration Department and DOLISA Hanoi do not automatically receive notice of corporate changes registered with the Department of Planning and Investment, so the employer must proactively update immigration records.
A second practical scenario: a Singapore-based holding company acquires a majority stake in a Hanoi-based manufacturing firm. The acquiring group seconds three managers to the Vietnamese entity. The managers'; work permits were issued under the previous ownership structure and reference the old corporate name and registration number. Post-acquisition, these permits are technically issued to a different legal entity. A labour inspection reveals the discrepancy, and the company faces fines and a requirement to reapply - causing a gap in legal status for the three managers.
The cost of non-specialist mistakes in this jurisdiction is measurable. Legal fees to remedy a non-compliant situation - including emergency applications, appeals and negotiations with DOLISA Hanoi - typically start from the low thousands of USD and can escalate significantly if deportation proceedings or re-entry bans are involved. Proactive compliance, by contrast, is considerably less expensive.
Understanding when to use one immigration route rather than another is the core value an immigration lawyer in Hanoi provides. The choice between a work permit route and an investor visa route, for example, has significant implications for processing time, documentary burden and long-term flexibility.
A third practical scenario: a French national is appointed as country director of a newly established representative office in Hanoi. The representative office is not a legal entity capable of generating revenue, which limits the available visa categories. The correct route is a DN visa sponsored by the representative office, followed by a work permit application under the manager/executive category. However, because representative offices cannot sign labour contracts under Vietnamese law, the employment contract must be structured carefully - typically as a contract with the foreign parent entity, with a secondment arrangement to the representative office. Getting this structure wrong at the outset creates problems when the work permit application is reviewed by DOLISA Hanoi.
For companies considering multiple expatriate deployments, a framework immigration policy - reviewed by a Hanoi-based immigration lawyer - saves significant time and cost over individual ad hoc applications. The policy should address visa categories, work permit eligibility assessments, renewal calendars, dependant sponsorship and the interaction with corporate changes.
The business economics of the decision are straightforward. A work permit application, including legal fees and agency costs, typically involves fees starting from the low thousands of USD. A temporary residence card application adds a further modest cost. Against this, the cost of a compliance failure - fines, emergency legal intervention, reputational damage and operational disruption - is materially higher. The procedural burden of maintaining compliance is manageable with proper systems in place; the burden of remedying non-compliance is not.
When comparing the work permit route with the investor visa route, the key differentiator is the individual';s role and equity position. If the foreign national is a genuine investor with a registered capital contribution, the investor route is faster and more flexible. If the individual is an employee - even a senior one - the work permit route is mandatory, and attempting to use the investor route without a genuine equity stake constitutes misrepresentation to the immigration authorities.

What happens if a foreign employee works in Vietnam without a valid work permit?
Working without a valid work permit is an administrative violation under Decree No. 28/2020/ND-CP. The foreign national faces a fine and, in repeated or serious cases, forced departure and a re-entry ban. The employer faces a separate fine for each unauthorised foreign worker. Beyond the financial penalties, the employee';s visa status may be revoked, requiring them to exit Vietnam and restart the entire application process from abroad. The practical disruption to business operations is often more costly than the fines themselves.
How long does the work permit and temporary residence card process take in Hanoi, and what does it cost?
A work permit application in Hanoi typically takes 15 to 30 working days from the date of submission of a complete file to DOLISA Hanoi, assuming the labour market test has already been completed. A temporary residence card application takes a further 5 to 10 working days after the work permit is issued. Legal and agency fees for the full process generally start from the low thousands of USD, depending on the complexity of the case and the number of documents requiring notarisation and legalisation. Urgent processing is not formally available, so timeline management is critical.
Should a foreign investor use the investor visa route or the work permit route to live and work in Hanoi?
The investor visa (DT) route is appropriate only where the individual holds a genuine, registered capital contribution in a Vietnamese enterprise meeting the thresholds under Decree No. 31/2021/ND-CP. It avoids the work permit requirement and the associated labour market test, making it faster and less document-intensive. However, if the individual';s primary role is operational or managerial rather than as a capital contributor, the work permit route is the legally correct path. Using the investor route without a genuine equity stake creates a misrepresentation risk that can result in visa revocation and re-entry restrictions. A Hanoi immigration lawyer can assess which route applies to a specific situation and structure the arrangement accordingly.
Vietnam';s immigration system rewards preparation and penalises improvisation. Foreign nationals and their employers in Hanoi face a layered set of obligations - visa categories, work permits, temporary residence cards and corporate sponsorship requirements - each with its own procedural timeline, documentary standard and renewal calendar. Getting the structure right from the outset is materially less costly than correcting errors under enforcement pressure.
