What is a letter of invitation?

A letter of invitation is an official document written by an individual or organisation inviting a person to visit, stay or attend an event in another country. These letters are commonly used for visa applications and immigration purposes.

Why you may need an apostille

You may require an apostille for:

  • Visa and immigration applications
  • Family or business visits abroad
  • International conferences or events
  • Residency or travel applications
  • Official verification for foreign authorities

An apostille ensures your letter of invitation is legally recognised in Hague Apostille Convention countries.

Can I legalise a letter of invitation?

Yes — UK letters of invitation can be legalised for international use, provided they meet the required format and certification standards.
