Letter of Invitation
Individuals requiring an official Letter of Invitation can request one through the Congress website. The Letter of Invitation does not financially obligate the Congress organizers in any way. All expenses incurred in relation to the Congress are the sole responsibility of the attendee.
If you travel to the Netherlands, you may need a visa. Whether you need a visa, and which visa, depends among other things on your nationality. And whether you want to stay in the Netherlands for shorter or longer than 90 days.
We recommend you to check on this platform if you require a visa or not.
Other documents are to be shown to enter the country. Please see more information here.
If you have questions after consulting mentioned websites, please contact the Visa Support Team.
