Visas

Check with your nearest Czech embassy whether you need a visa to travel to Prague, Czech Republic. Citizens of USA, Canada, UK, EU countries and several other countries do not need a visa. If you need a visa: the Czech Republic (aka Czechia) is a part of the Schengen Area so you can enter it with a Schengen visa (i.e. a visa for any of the Schengen countries). However, there are rules to which country you should apply for the Schengen visa so you should check them out. In most cases of a travel for STOC 2025, it will be a Czech embassy.

The local organizers can provide you with an invitation letter or you can get a letter from ACM, see below.
