  • Please note that each individual requesting an invitation letter must fill out a separate form.

  • OSA Management reserves the right to request further information regarding the company or affiliation of the attendee to ensure the validity of requests.

If you need a travel visa, begin the visa application process now! The application process can sometimes take a while. We strongly encourage you to apply for your visa as early as possible.  All foreign nationals wanting to visit France must be able to submit statutory documentary evidence at the border for the reasons for their stay, their means of support and accommodation arrangements.

As a rule, unless you are exempt, you are required to have a visa. It must be applied for from the relevant French embassy or consulate in the applicant’s country of residence. Visit the France Diplomatie website for more information on visa requirements.
