The recent agreement between the UK and the EU has allowed for visa-free travel for short visits – up to 90 days in any 180-day period (excluding any trips to Ireland, Croatia, Bulgaria and other non-Schengen states, for which there's no limit on the length of trip). Brussels has said that British visitors will be visa-exempt 'third-country nationals' initially, which means that they need not apply in advance. But within a year or so, British citizens will be subject to the new European Travel Information and Authorisation System (ETIAS), which the EU is working to impose no later than 2022.
