Foreign nationals who are subject to visa requirement and want to enter the Schengen area, with Slovakia being their target destination, must file a visa application with the competent Slovak embassy or consulate general. Foreign nationals legally residing in a third country (i.e. other than the country of their citizenship) may apply for a visa at the embassy/consulate general competent for the country of their current residence.
More information about the visa is available on the web page of the Ministry of Foreign and European Affairs of the Slovak Republic
When applying for a visa, the Slovakia will require a letter of invitation from ISSS 2018. Therefore, we kindly ask that you email your request for us to send you the official letter of invitation with the text that the letter should contain. The official letter of invitation should be requested several months in advance of the June 2018 conference, as it may take up to 6 months to get the visa processed. If you intend to submit an abstract to the conference, we encourage you to submit the abstract prior to requesting the official letter of invitation.
