Understanding Invitation Letters for Cambodia E-visa

An invitation letter is a formal document issued by a Cambodian individual, organisation, or business entity inviting you to visit Cambodia for specific purposes. While not always mandatory for e-visa applications, invitation letters provide additional credibility and can help demonstrate the legitimacy of your visit to Cambodian immigration authorities.

Invitation letters serve as supporting documentation that clarifies your travel purpose, accommodation arrangements, and local connections in Cambodia. They are particularly valuable for business e-visa applications and can help address potential concerns about your visit's authenticity.
