Quick answer
About this website
Vietnam Passport & Visa Guide is a website of Tu Do Travel Trading and Service Company Limited (Tu Do Travel), a private company not affiliated with any government. The information helps you understand and prepare your application; it does not replace the instructions of the competent authority. Vietnamese passports are issued by Vietnam's immigration authorities; visa decisions are made by the authorities of the country you visit.
Approved sources only
The website uses 44 official sources. The list is kept in a single place in the code; adding a new source needs the reviewer's approval first. A guide citing a source outside the list cannot be built.
Before a page is published
Research
We read the detailed official page or legal document itself and record the link and the date. News reports, forums and other service providers' websites are never used as sources.
Store the figures
Passport fees, the visa-free country list and each country's official authority are stored in one place, each with its source and check date. Guides read the figures from there; nobody retypes them.
Write
Short sentences and tables, a quick answer at the top and the sources under the title. Points the source does not settle go in a “Please verify” box. We never copy other websites.
Automatic checks
Every time the website is built, the system runs the checks listed below. A failed check stops publication.
Review
New pages carry a “Pending review” label, are hidden from search engines and left out of the sitemap. Once the reviewer has read and approved a page, it becomes “Reviewed”.
Regular review
Figures are reviewed every month; anything not checked for 45 days triggers a warning. When an authority changes a rule or a fee, we update the guide.
What the system checks automatically
check:banned- Blocks wording that promises a visa outcome, published service fees and old email addresses in all content.
check:keywords- Each page has exactly one main keyword, not shared with another page; English and Vietnamese versions are paired correctly.
check:data- Figures in the data sets have the right format, an approved source and a check date; warns when a check is more than 45 days old.
defineArticle- Each guide must have approved sources, a check date, questions and answers, and an address matching the keyword map.
check:built- After the build: no broken links, no banned wording in visible text, one main heading per page, correct page language.
check:links- Checks the live website: internal links, redirects and status codes.
When the source is unclear
If an official source does not state something clearly, the guide says so in a “Please verify” box and asks you to check with the competent authority, rather than guess. Where sources disagree, we log the difference in our internal research notes and the reviewer decides how to present it.
English pages
The website is written in Vietnamese. English versions exist for the main pages only and use the same sources and the same review process.
Who reviews the content
Content is written by the Tu Do Travel team and reviewed by Thanh Lee, Chief Executive Officer of Tu Do Travel, before it is indexed. The reviewer checks figures against the sources, the wording and the notes for readers.
Information and services kept apart
- Guides, self-help tools and questions and answers are free and enough to apply on your own.
- We never list our service fees; we only show government fees with a source. Our help is quoted per case.
- We do not promise or predict passport or visa outcomes, and we never suggest untruthful documents.
