The Saudi Arabia Business Invitation Letter is a document mandatory for every person who wishes to travel to Saudi Arabia for business purposes. Since the Saudi immigration system is based on the idea of corporate sponsorship, a company operating and registered in the KSA must sponsor the visa. Obtaining the letter is followed by the application for a business visa.

The invitation letter is issued entirely online and includes some personal information of the applicant, details of both the inviting company and the sending company, the type of requested visa, and its validity period. Most of the invitations are written partially in English and Arabic.
