Please note that you must be registered for the event before requesting a visa letter. It can take up to 24 hours for an event registration to be processed. During that time, you will not be able to request a visa letter.

Please fill out all information below as accurately as possible. Otherwise, we may need to contact you for additional details, which will delay the 72 hour turnaround time it typically takes to process a visa letter request.

Please note that some countries in which we hold events require an organization within that country to provide a visa invitation letter. Thus, the Linux Foundation must use a local third party to process letter requests from time to time. By filling out this form you are authorizing the Linux Foundation to share your details with a 3rd party vendor as needed to process an invitation request.

All visa letter requests must be submitted no later than two weeks prior to the event. Any visa letter requests made after the two-week deadline cannot be guaranteed.
