Vietnam e-Visa “Portrait photo was captured from another source” warning

What the warning is about

“Portrait photo was captured from another source” is a warning associated with the portal’s comparison of the portrait and the passport photo. It should not be treated as the same problem as a rejected extension, a file-size message, or the script-tag upload message.

The wording does not tell us exactly which image feature caused the warning. The portal’s internal reason is unresolved.

What is officially known about face comparison

The official user manual shows portrait and passport data-page uploads, automatic personal-data extraction, and a “Face compare / Match” step. It also shows that an invalid passport photo can block submission.

That is the official fact: face comparison exists in the documented portal flow. The manual does not publish an algorithm, similarity score calculation, exact threshold, or minimum matching percentage.

What may contribute — possibilities, not official rules

• A substantial difference between the current portrait and an older passport photo.
• Different lighting, shadows, pose, expression, or glasses between the two images.
• A blurred passport face, a very small passport portrait, glare, or strong compression.
• A file that is technically readable to a person but difficult for the portal’s image processing to interpret.

Use a truthful current portrait — do not edit your face to match

Do not digitally alter your face to look more like the passport photo or try to bypass the portal’s face matcher. Use a current portrait that accurately represents you and follow the official photography instructions.

If your appearance has changed substantially since the passport was issued, the portal may still require an official decision or updated document. This Tool cannot resolve that identity question.

What the Tool can and cannot do

• It can help with appropriate framing, resolution, JPEG quality, and a clean export.
• It can help keep the passport data page complete, readable, and free from unnecessary degradation.
• It cannot control the official face-matching algorithm, score, or acceptance threshold.
• It cannot make an old passport portrait match a current appearance or guarantee a portal decision.
