Lack of valid documents in Vietnam, refusal of notarization, and inability to obtain consular legalization are very common issues for foreigners preparing documents to work abroad. This not only causes delays but may also result in losing work permit opportunities if not handled properly.
Consular legalization is the process of certifying the validity of documents issued in one country so that they can be recognized and used in another country.
This is almost always required when applying for a work permit, labor visa, or completing legal procedures abroad such as in Taiwan, Korea, or Japan.
In principle, for documents to be legalized, they must:
If any of these elements are missing, the application is very likely to be rejected from the beginning.

This is the most common reason. Many foreigners who previously worked in Vietnam face situations where:
Under Vietnamese regulations on notarization and certification, documents without clear signs of authenticity cannot be certified, and therefore cannot proceed to consular legalization.
Many applicants are refused notarization because:
Vietnamese law allows notaries to refuse notarization if there is insufficient basis to verify the legality of the document.
Some individuals prepare their own confirmation letters or rely on third parties without proper authority. Such documents typically:
This is often the biggest obstacle:
In these cases, it is usually not possible to supplement documents through conventional methods.
Each country (Taiwan, Korea, Japan, etc.) has its own document requirements. For example:

The answer is: not necessarily.
In practice, many cases that seem impossible can still be resolved — but only with the right legal approach tailored to each specific situation.
The key is to clearly identify: where the issue lies and the legal reason behind it.
If you cannot obtain documents directly from your former employer, you may consider:
Possible solutions include:
Although complex, this situation may still be addressed by:
If your documents have been rejected repeatedly, the issue is often not simply “missing documents” but rather:
Continuing to resubmit the same documents without adjustment will likely lead to the same outcome.

Under Decree No. 111/2011/ND-CP, documents eligible for consular legalization must:
In addition, notarization and certification regulations in Vietnam require:
Failure to meet these conditions provides a clear legal basis for rejection.
A common mistake is:
Rejected once → resubmit the same documents → rejected again
Each case should instead be:
This is particularly critical for work permit applications, where requirements are often strict.

DEDICA has successfully handled cases involving:
Being refused notarization or consular legalization does not necessarily mean you have lost your opportunity to work abroad. In many cases, the issue lies in how the documents are prepared rather than the documents themselves.
However, each case is unique and cannot be solved with a one-size-fits-all approach.
Note: Depending on the specific case, the applicable solutions and success likelihood may vary. A detailed legal assessment is required before determining the appropriate course of action.
