Brexit and Visas

At the time of this writing, the official position is that nothing will change for visitors from the EU (and most other European countries), even in case of a “no-deal” Brexit.
But, as this may still change, please check with the official site of the UK government regarding “What you’ll need to do to visit the UK after the UK leaves the EU, including whether you’ll need to apply for a visa.”
