Japan Work Visa Rejection Reasons and Common Mistakes by Vietnamese Applicants

Most Japan work visa rejections are preventable. The Japanese Embassy and Immigration Services Agency do not publish official rejection rates by nationality, but the patterns are consistent: the applications that fail share a small set of repeatable errors. For Vietnamese applicants specifically, several of these errors are tied to how Vietnam handles documents — and to the gap between what agencies promise and what immigration authorities actually require.

Rejection Reason 1: Job-Degree Mismatch for the Engineer Visa

The most common reason professional visa (Gijinkoku) applications fail is a mismatch between the applicant's degree field and the duties described in the Japanese job offer.

Japanese immigration officers review this alignment rigorously. A computer science graduate applying for a software developer role will have no problem. That same graduate applying for an international marketing coordinator role — even if the employer genuinely wants them — faces immediate scrutiny.

The fix is not to lie on the job description. It is to work with your employer to write the job description accurately so it emphasizes the technical elements that connect to your degree. If you have a business degree, lean into data analysis, project management, or international liaison duties rather than pure engineering tasks.

For Vietnamese graduates from recognized institutions such as Hanoi University of Science and Technology (HUST), Vietnam National University (VNU), or FPT University, the university itself is not typically a problem. The degree content alignment is what gets reviewed.

Age limit note for the engineer visa: There is no fixed age limit for the Gijinkoku (Engineer/Specialist) visa. The SSW Type 1 similarly has no age limit in law, though some specific industries may have practical health and fitness requirements that indirectly affect older applicants.

Rejection Reason 2: Untranslated or Improperly Notarized Documents

Vietnam-issued documents must go through a specific chain before they are accepted by Japanese immigration. This is not a bureaucratic formality — applications are rejected when this chain is broken.

The required chain for Vietnamese documents:

1. Original document — issued by the Vietnamese authority (university, Ministry of Justice, local police)
2. Certified Vietnamese translation — or the original is already in Vietnamese, which is fine
3. Certified Japanese translation — done by a qualified translator; the translation office stamps and signs each page
4. Notarization (Công chứng) — confirms the translator's signature is authentic; done at Vietnamese notarization offices

Where Vietnamese applicants most often break this chain:

• Using a translation that is accurate but done by an uncertified individual (a bilingual friend, for example)
• Submitting copies of documents without proper certification
• Forgetting that degrees issued by technical colleges (cao đẳng) require the same treatment as university degrees
• Not realizing that the lý lịch tư pháp (judicial record certificate) has a six-month validity window — if it expires before the COE is submitted, you need a new one

Rejection Reason 3: Using an Unverified or Delisted Sending Organization

For SSW applicants, the sending organization (phái cử) must appear on the OTIT portal in Japan as an approved Vietnamese sending organization. If the company has been suspended or removed from that list — even if they still have a Vietnamese DOLAB license — applications tied to them will be rejected.

Agencies get removed from the OTIT list for violations including charging illegal fees, falsifying documents, or failing to support workers after arrival. The removal is published on the OTIT website, but workers are rarely told.

This is one reason why checking otit.go.jp yourself — before you sign anything — is not optional. Agencies with legitimate operations will show their OTIT registration number readily.

Rejection Reason 4: Failed or Expired JPETS Tuberculosis Screening

Vietnam is one of six countries where Japan's MHLW requires mandatory tuberculosis pre-screening (JPETS) before visa issuance. The TB Clearance Certificate from a designated Panel Clinic is valid for 180 days from the X-ray date.

Applications that arrive without this certificate, or with an expired one, are rejected outright. This catches Vietnamese applicants who complete the screening early in the process but then experience delays — the 180-day window can close before the COE arrives from Japan.

The fix is to time the JPETS screening to coincide with when your COE application has been filed in Japan, not when you first begin preparing your documents.

Rejection Reason 5: Inconsistencies in Employment History or Income Documentation

The immigration officer constructs a picture of your professional history from multiple documents: your resume, your employment contract, your employer's registration documents, and any references. Inconsistencies between these sources — a gap in employment history that is not explained, a salary figure that conflicts between documents, a job title that does not match the role description — trigger requests for additional documentation or outright rejection.

For applicants going through the engineer route without an agency, this self-review step is critical. Have someone unfamiliar with your situation read the full package and flag anything that raises a question.

Common Mistakes That Do Not Cause Rejection But Cause Serious Delays

Not everything that goes wrong results in an immediate rejection. Several mistakes add months to the process:

Submitting the COE application to the wrong Regional Immigration Bureau. The COE must be filed at the bureau covering the area where the employer is located in Japan, not where the applicant lives in Vietnam.

Employer delays in submitting the COE. Once you hand over your documents to the employer in Japan, you have no direct control over when they file. Some employers, particularly smaller ones unfamiliar with the process, wait weeks before submitting. Establish an expected filing date in writing before you send anything.

Degree certificates that have not been verified through VN-NARIC. For professional visa applications, some Regional Immigration Bureaus in Japan now request the VN-NARIC digital verification certificate (available at naric.edu.vn) in addition to the notarized copy. This is not yet a universal requirement, but it is increasingly common.

Who Can Apply Without a Degree

The SSW route is specifically designed for non-degree holders. If you have no university degree and are between 18 and 35 (the practical range, not a legal requirement), the SSW pathway via a DOLAB-licensed agency is the standard route.

The Gijinkoku (engineer/professional) visa can technically be obtained without a degree if you have ten or more years of professional experience in the relevant field — but this is extremely difficult to document convincingly, and immigration officers scrutinize it carefully. For most non-degree holders in Vietnam, SSW is the realistic route.

College graduates (cao đẳng — associate degree level) occupy a gray area. Some have qualified for the professional visa under the "Specialist in Humanities" sub-category when the employer could demonstrate that the two-year program provided the relevant specialization. This is not guaranteed and depends heavily on how well the employer's attorney can frame the application.

How to Minimize Your Risk Before Applying

Read every document in your application package as if you are the immigration officer. Ask: does this make logical sense? Does the job description match the degree? Is every translation certified? Is every Vietnamese document within its validity window?

For the SSW route specifically: verify your agency on OTIT before you pay a single dong. For the engineer route: have your employer's HR team confirm they have filed COE applications before and know which Regional Immigration Bureau to use.

The Vietnam to Japan Work Visa Guide includes a pre-submission self-audit checklist that walks you through every document in the package and the specific checks that catch the errors listed above before they become rejections.
