A Vietnamese work permit belongs to a specific job with a specific employer, so it does not move with you. If you change employer, the new employer must obtain a new permit, and your work visa and temporary residence card, which were sponsored by the old employer, generally have to be replaced as well. If you stay in the same job, the permit can be extended once, for up to two years, before a new permit is needed. When you leave, the permit ends and the employer has duties to report it.
Most foreign workers go through at least one of these transitions: a contract renewal, a promotion, a move to another company, or a final departure. Each one touches three separate documents, the permit, the visa or residence card, and the labour contract, which expire on their own timelines. This guide explains how they interact and how to avoid a gap where you are in Vietnam with no valid basis to work or stay. Confirm the details of your case with HR, the provincial labour authority and the immigration office, because procedures are revised regularly.
Three documents, three clocks
It helps to keep a simple picture in mind. The work permit allows you to work for one employer in one position. The visa or temporary residence card allows you to stay in Vietnam, and for workers it is sponsored by that same employer. The labour contract governs the relationship between you and the employer. They are linked, but they are not the same document and they do not end automatically on the same day unless someone has planned it.
Under the Labour Code, the term of a foreigner's labour contract cannot exceed the term of the work permit. In practice, employers align the contract and the permit, and the residence card is issued for a period no longer than the permit. When one of the three is about to run out, the others usually are too, and all three need attention at the same time.
The practical rule is to write down the expiry dates of all three on one page, plus your passport, and to start any renewal well before the earliest date. Applications for extension have to be filed within a window before the permit expires; ask HR for the exact window under the current decree and put a reminder in your calendar months ahead.
Staying in the same job: extension and reissue
If you are staying with the same employer in the same role, the permit can be extended. The Labour Code allows one extension of up to two years. The employer files the extension, usually with a reduced set of documents: an updated health certificate, evidence that the employer still needs a foreign worker in the position, and the existing permit. When the single extension has been used, the employer applies for a new permit instead, which may require more documents again.
Some changes do not need a new permit but do need the existing one to be reissued: a change of your name or passport, a change to the employer's name or address, or certain changes in the workplace. A promotion or a new role can be a grey area. Moving from teacher to head of department, or from engineer to project manager, may be close enough to reissue, or different enough to need a new permit. Ask HR to check before the new title takes effect.
Remember the visa and residence card. When the permit is extended, the employer then extends or renews your residence card to match. Two applications, two offices, so the timing has to allow for both.
Moving to a new employer
Changing employer is the transition that catches people out most often, because it involves both sides. The usual order looks like this.
- Agree terms with the new employer, including the start date, before you resign. Make sure it understands that it must apply for a new permit and sponsor your visa or residence card.
- Check what documents can be reused. Legalised degrees and experience letters generally remain usable; the criminal record check and health certificate may need to be renewed if they are no longer recent.
- Give notice according to your contract and the Labour Code. Notice periods depend on the type of contract. Leaving without proper notice can cost you final pay and the cooperation of your old employer.
- The new employer applies for the new permit. Some steps may be simplified when you have recently held a permit for a similar position, but the application is still a new one.
- Your old permit ends and is reported. The old employer generally recovers the permit and notifies the authority when your contract ends.
- Your residence status is changed. The old residence card, sponsored by the old employer, is cancelled, and the new employer sponsors a new visa or card. Ask the immigration office whether this can be done without leaving Vietnam in your situation.
- Start work only when the new permit is issued.
The awkward period is between the last day at the old job and the first day at the new one. During it you may have no valid work permit, and your residence card may no longer have a sponsor. Plan the dates with both employers so that this gap is short and covered by a valid visa.
Leaving your job without a new one lined up
If you resign or your contract ends and you do not have another job, the permit ends with the contract. Your residence card, sponsored by the employer for the purpose of work, also loses its basis. In practice, foreign workers in this situation either leave Vietnam, switch to a visa that fits a different purpose, or secure a new job and sponsor quickly. What you should not do is stay on the old card as if nothing had changed.
Speak to the immigration office or a qualified adviser about your options before your last day. Depending on your situation, you may be able to stay for a period on a different visa, for example as a visitor or on a family basis if you are married to a Vietnamese citizen. Rules differ by category and change from time to time, so do not rely on what worked for a colleague.
Before you leave the job, collect what you will need later: a signed reference letter stating your title, dates and duties, a copy of your work permit, your final payslips, and confirmation of social insurance and tax withheld. Ask the employer how it will finalise your personal income tax for the year. These documents are much harder to obtain once you have left.
Tax, insurance and your family when you move on
A job change is also a tax event. Your old employer withholds personal income tax up to your last month, and the year's tax may need to be finalised, either by an employer on your behalf or by you directly, depending on how many employers paid you during the year and whether you remain tax resident. If you leave Vietnam for good, tax finalisation before departure is the clean way to close the year. Ask both employers who will handle it, and keep every payslip and withholding certificate.
Social insurance contributions also stop at the old employer and, if you are covered, restart with the new one. If you leave Vietnam permanently, ask about the rules for any lump-sum payment of social insurance that may be available to foreign workers, because they depend on the scheme and the current law.
Finally, your family. Spouses and children holding dependent visas or residence cards linked to your status are affected by your change too. When your sponsor changes, their documents usually need to be redone with the new employer as the basis. Build their applications into the same timetable rather than discovering the issue at their next border crossing.
When the employer causes the problem
The company closes or is restructured. A permit ends when the employer ceases operations. If your company is closing or merging, ask early how it will handle your permit and contract, and start looking for a new sponsor before the last month.
The employer refuses to release you. An employer cannot keep you in a job against your will, but you must follow the notice rules. If an employer withholds documents or final pay, keep everything in writing and consider the labour dispute channels described in our guide to employment contracts.
The employer forgets to renew. It happens, especially in small companies. You are the one who loses status, so track your own dates and remind HR in writing.
The employer asks you to keep working after the permit expires. Do not. Working on an expired permit is working without a permit. Insist that the extension or new permit is issued first.
A note on long careers in Vietnam
Foreigners who have spent many years in Vietnam often reach a point where moving from permit to permit feels fragile. Some build a stronger basis over time: investing in their own company, marrying a Vietnamese citizen, or meeting the conditions for permanent residence in the limited circumstances the law allows. Each route has its own rules and is covered elsewhere in this guide.
Each of those routes takes time to prepare, and the right moment to explore them is while you still hold a stable permit, not in the weeks after a contract ends. A conversation with a lawyer who handles foreign residents, held a year before you need it, costs little and often changes the plan.
Until then, the best protection is an organised record: copies of every permit and residence card, every contract, and confirmations of tax and social insurance. When an official or a new employer asks about your history, a clean file answers the question in minutes. Gaps in that file are what lead to long conversations.
Câu hỏi thường gặp
Can I transfer my work permit to a new employer?
No. A Vietnamese work permit is tied to the employer, position and workplace, so a new employer must apply for a new permit. Some documents from your previous application can often be reused, which shortens the process, but the permit itself does not move with you.
How many times can a work permit be extended?
Under the Labour Code, a work permit can be extended once, for a maximum of two years. After that, the employer applies for a new permit. The permit's term is normally aligned with your labour contract and assignment.
What happens to my residence card if I quit my job?
A residence card issued for work is linked to the employer that sponsored it. When the job ends, the card loses its basis and is normally cancelled, and you need a visa or card for a different purpose or a new sponsor. Ask the immigration office about your options before your last day.
Can I start at my new job while the new permit is processing?
No. You should not work for the new employer until its permit for you has been issued. Use the waiting period for handover at your old job or for preparing documents, and make sure you hold a valid visa throughout.
Does a promotion require a new work permit?
Sometimes. A small change may only require the existing permit to be reissued, while a move to a substantially different position may require a new permit. Ask HR to check with the provincial labour authority before your new title takes effect.
What should I collect before leaving a job in Vietnam?
A signed reference letter with your title, dates and duties, copies of your work permit and contract, final payslips, and confirmation of social insurance and personal income tax withheld. These help with your next permit application and with tax finalisation.
