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.
What is Consular Legalization and Why is It Important?
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:
- Be lawfully issued in Vietnam
- Bear valid signatures and official seals
- Be properly notarized or certified in accordance with regulations
If any of these elements are missing, the application is very likely to be rejected from the beginning.

Why Are Documents Rejected for Consular Legalization?
Missing Valid Signature and Official Seal
This is the most common reason. Many foreigners who previously worked in Vietnam face situations where:
- They are not issued an employment confirmation letter by their company
- The document lacks the legal representative’s signature
- The company’s official seal is missing
Under Vietnamese regulations on notarization and certification, documents without clear signs of authenticity cannot be certified, and therefore cannot proceed to consular legalization.
Documents Are Not Notarized or Do Not Qualify for Notarization
Many applicants are refused notarization because:
- The content is unclear or the origin cannot be verified
- Only scanned or printed copies are provided without originals
- The document format does not meet legal standards
Vietnamese law allows notaries to refuse notarization if there is insufficient basis to verify the legality of the document.
Documents Not Issued by Competent Authorities
Some individuals prepare their own confirmation letters or rely on third parties without proper authority. Such documents typically:
- Cannot have signatures certified
- Are not accepted for consular legalization
Former Employer No Longer Exists or Refuses to Cooperate
This is often the biggest obstacle:
- The company has been dissolved or ceased operations
- The legal representative cannot be contacted
- The company refuses to issue supporting documents
In these cases, it is usually not possible to supplement documents through conventional methods.
Failure to Meet Foreign Country Requirements
Each country (Taiwan, Korea, Japan, etc.) has its own document requirements. For example:
- Employment certificates must contain specific details
- Information on working period, position, and job title may be required
If documents from Vietnam do not meet these requirements, they may still be rejected even after legalization.
Does Rejection Mean There Is No Solution?
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.
Practical Solutions for Different Scenarios
Missing Employment Confirmation from Company
If you cannot obtain documents directly from your former employer, you may consider:
- Using alternative documents (labor contracts, payslips, work emails, etc.)
- Preparing explanatory statements with appropriate certification
- Assessing acceptance by foreign authorities
Documents Not Eligible for Notarization
Possible solutions include:
- Reviewing and adjusting document content to meet legal standards
- Re-drafting documents in proper legal format
- Identifying the correct authority to issue or certify documents
Company Has Been Dissolved
Although complex, this situation may still be addressed by:
- Retrieving archived records from state authorities (if available)
- Using alternative supporting documents combined with explanations
- Structuring the dossier to meet the receiving country’s requirements
Multiple Rejections
If your documents have been rejected repeatedly, the issue is often not simply “missing documents” but rather:
- Incorrect approach to preparing the dossier
- Misunderstanding of legal requirements at each stage
Continuing to resubmit the same documents without adjustment will likely lead to the same outcome.

Important Legal Notes
Under Decree No. 111/2011/ND-CP, documents eligible for consular legalization must:
- Be issued by competent authorities
- Not contain signs of forgery
- Not violate Vietnamese law
In addition, notarization and certification regulations in Vietnam require:
- Valid original documents
- Verifiable identity of the signatory
- Clear and transparent content
Failure to meet these conditions provides a clear legal basis for rejection.
Why You Should Evaluate Your Documents Before Reapplying
A common mistake is:
Rejected once → resubmit the same documents → rejected again
Each case should instead be:
- Carefully analyzed to identify legal issues
- Reconstructed with appropriate alternatives
- Assessed for acceptance likelihood
This is particularly critical for work permit applications, where requirements are often strict.
