One Visa Center publishes free guides on visas, passports, study abroad and travel planning. Immigration decisions affect people’s money, time and future, so this page explains who writes our content, how we research it, how we use AI tools, and how to tell us when something is wrong.

Who writes our guides

Articles are published by the One Visa Center Editorial Team and, on some older articles, by named contributors. We are an independent information site. We are not a law firm, a government agency or a visa agent, and we do not submit applications on anyone’s behalf.

How we research and fact-check

• Official sources first. We check fees, eligibility rules, processing times and deadlines against official government sources, such as the U.S. Department of State, USCIS, GOV.UK, IRCC (Canada), the European Commission and national immigration authorities. We link to these sources in our articles so you can check them yourself.
• Dated information. Newer guides show the date we last checked them against official sources. Rules can change at short notice, so we always tell you to confirm details on the official website before you apply or pay.
• No guesswork on numbers. If a rule is proposed but not final, or official sources disagree, we say so rather than presenting it as settled.
• Practical value. We aim to add something useful beyond a summary of government pages, such as step-by-step processes, worked examples, cost tables, common mistakes and scam warnings.

How we use AI tools

We use AI tools to help with research, outlining, drafting and editing some articles, and to create some illustrations. Our rules for using them are:

• Facts are checked against official sources before we publish. We don’t publish AI output that hasn’t been reviewed.
• We don’t use AI to create fake people, reviews or credentials. Featured images on many articles are AI-generated illustrations. They are not photos of real people, places or documents.
• We don’t mass-produce pages. We publish guides because readers need the information, not to fill the site with pages for search engines.

Updates and corrections

We review guides when rules change and update them with a new “last checked” date. We only change a date when we have actually reviewed the content. Some older articles on the site were written before this policy and may be out of date. We’re working through them, starting with the most-read guides.

If you spot an error or an outdated rule, please tell us through our Contact page. We’ll check it against the official source and correct the article if needed.

Independence and advertising

We may show ads and we sell our own digital guides and toolkits. These never decide what we say about visa rules, and no government, agent or advertiser pays to change our content.

Not legal advice

Our guides are general information. They aren’t legal advice and they don’t replace advice from a licensed immigration lawyer or the official authority handling your case. If your situation is complex, for example a past refusal, overstay or criminal record, please speak to a qualified professional.
