Every UK Visitor Visa category shares a common core of documents, but each one also has a specific extra requirement tied to its purpose — a business invitation letter, a hospital treatment letter, event registration proof, and so on. This guide lists both, so you can build a complete document folder before booking your VFS Global appointment.
This guide is for Indian applicants who want one place to check every document a UK Visitor Visa needs. UK Home Office rules and processing timelines can change — treat this as a practical planning reference and confirm final requirements on gov.uk before applying.

Common mistakes Indian applicants make
The most common mistake is submitting the universal document set without the one extra requirement specific to your category — for example, a business visitor application with no company invitation letter, or a medical visa with no hospital treatment letter. Reviewers look for a complete, category-matched file, not just generic paperwork.
