Lacking valid documents in Vietnam, being refused notarization, and being unable to complete consular legalization — this situation has caused many people to almost lose their opportunity to obtain a work permit abroad.
In practice, many foreigners who have worked in Vietnam face this exact issue. You genuinely worked and gained real experience, yet you are unable to prove it in a legally acceptable way.
The problem is not that you “lack experience,” but that you lack documents that meet legal requirements to prove that experience.

Many clients come to us with similar situations: they previously worked in Vietnam, but their former company has ceased operations, refuses to cooperate, or simply does not respond. As a result, they cannot obtain a work experience confirmation letter with proper signature and company seal.
Meanwhile, self-prepared documents or internal emails are generally not accepted for notarization or certification. When submitted for consular legalization, these documents are again rejected due to not meeting formal requirements.
This creates a vicious cycle:
No valid documents → Cannot notarize → Cannot legalize → Not eligible for a work permit.
This is a point many people misunderstand.
Under Vietnamese law on notarization and certification, authorities do not verify the truthfulness of a document’s content if it does not have a clear and lawful origin.
Specifically:
This means:
If you do not have documents issued by your former company (with proper signature, seal, or legal confirmation), it is almost impossible to ask a government authority to “confirm it for you.”
Many people assume that translation and legalization are enough. However, under Decree 111/2011/ND-CP, consular legalization only applies to documents that are already valid in terms of form and origin.
In other words:
If your documents do not meet these conditions, consular authorities will reject them.
Not necessarily.
However, it is important to understand that there is no one-size-fits-all solution. Each case requires a tailored approach.
Below are some approaches we typically analyze with clients. These options must be carefully evaluated before application.
Even without an official confirmation letter, you may still have:
These documents cannot fully replace an experience certificate, but they can help build a logical and consistent file to support your explanation.
Some countries or authorities may consider:
However, in Vietnam, certification of a signature does not mean the content is verified as true. Therefore, the value of such documents depends on the receiving authority abroad.
This remains the best option if still feasible.
In practice, many cases that seem “impossible to resolve” can be improved with legal support:
Each country (Taiwan, South Korea, Japan, etc.) has different standards for proving work experience.
Some may be more flexible if:
However, it is important not to assume that any approach will be “automatically accepted.”

Through handling many cases, we have observed several common mistakes:
These mistakes not only lead to rejection but may also negatively affect your credibility in future applications.
The issue is not just whether you “have documents,” but whether those documents carry legal value.
An invalid document:
On the other hand, a properly structured file — even if not perfect — may still have a chance if it is logical and compliant.
In “non-standard” cases like these, the role of a lawyer is not to “create documents,” but to:
