Document preparation is the core of any DTV application. Even when the content is correct, formatting inconsistencies or missing details can trigger follow-up requests. Knowing the common pitfalls in advance gives you the best chance of clearing review on your first submission.

What you'll learn: The types of mistakes most often seen in DTV applications, which documents are most error-prone, and how to self-check before submitting.

Error-Prone Document Categories

Passport

Common mistakes:

  • Passport expiry is less than 6 months from the application date
  • Photo page scan is dark, tilted, or has a cut-off corner
  • MRZ (machine-readable zone) is not legible in the scan

Solution: Verify the expiry date before applying. Scan flat in a well-lit area, and confirm the full document — all four corners — is captured.

Applicant Photo

Common mistakes:

  • Background color does not meet requirements (typically white or off-white)
  • Dimensions do not meet pixel requirements
  • Head is turned or eyes are not facing forward
  • Using an outdated photo

Solution: Review the e-Visa system's photo requirements before applying and prepare a compliant photo accordingly.

Name and Passport Number Inconsistencies Across Documents

Common mistakes:

  • Name on application form differs from passport (e.g., "TANAKA HANAKO" vs "HANAKO TANAKA" — different ordering)
  • Passport number is not consistent across multiple documents
  • Some documents still show a maiden name after marriage

Solution: Standardize the full name and passport number across all documents to match the exact format shown in the passport.

Bank Balance Certificate

Common mistakes:

  • Certificate was issued too long ago (e.g., months before the application)
  • Not issued in English
  • Account holder name does not match the passport name
  • A large deposit made immediately before obtaining the certificate may be difficult to explain

Solution: Obtain the certificate in English shortly before applying (within one to two weeks). Confirm that the account holder name matches the passport name.

Employment Contract / Service Contract

Common mistakes:

  • Only exists in Japanese with no English version
  • Contract has no signature or seal
  • Submitting an expired contract
  • No mention that remote work from Thailand is permitted

Solution: Obtain an English-language version from your employer or client. Confirm — or ask to add — language confirming that remote work is permitted.

Acceptance Letter (Soft Power route)

Common mistakes:

  • Issuing institution information (name, address, signatory) is unclear
  • Activity period and content are vague
  • Applicant's name does not match the passport format

Solution: Confirm with the issuing facility that the institution details, activity specifics, dates, and the applicant's name (matching the passport exactly) are all clearly stated.

Health Insurance Documentation

Health insurance documentation is not listed among the primary required documents in major embassy DTV official guidance, but depending on the embassy and timing, it may be requested as an additional verification item. It's worth preparing in advance:

  • Confirm whether your insurer can issue an English-language certificate
  • Check coverage amount and period
  • Check whether your application embassy's guidance mentions insurance requirements

FAQ

Q. If there's a problem with a document, will my application be rejected? A. Depending on the issue, you may receive a request for additional documents rather than an outright rejection. Minor issues are often resolved with a follow-up response. Serious issues — falsification, critical missing information — can lead to rejection.

Q. If I receive a follow-up request, will the review continue? A. If it's a request for additional documents, the review continues after you respond. In some cases, you may need to withdraw and reapply — follow the instructions in the notification.

Q. Do all Japanese-language documents need translation? A. Whether translation is required depends on the embassy. English submission is the standard, so consider attaching an English summary or explanation alongside any Japanese documents.

Q. Is it a problem to increase my balance just before applying? A. If the balance shown in the certificate significantly exceeds your typical account balance, you may be asked to explain the source. Avoid creating a temporary artificial balance through last-minute transfers.
