This is the process for applying for a Schengen visa for 5CC (no liability for the correctness, completeness, or quality of the information provided):
Full details are available on the website of the European Commission, Migration and Home Affairs.
Delegates should begin the visa application process early, including a request for a letter of invitation, ideally at least six months before the conference.
The 5CC 2024 letter of invitation does not financially obligate the conference organizers in any way and nor does it guarantee entry to Portugal. All expenses incurred in relation to the conference are the sole responsibility of the delegate.
In the case that your visa should be declined, we do not offer refunds of the registration fee, but will gladly apply the registration towards the next 5CC conference.
