If you’re a tourist, you do not need a visa for short trips to EU countries, Switzerland, Norway, Iceland or Liechtenstein. You can stay for up to ninety days in any one hundred and eighty-day period.
If you visit more than one of these countries within one hundred and eighty days, check that you do not spend more than ninety days across all the countries you visit. That’s because many countries apply the ninety-day limit as a group.
There are different rules for Bulgaria, Croatia, Cyprus and Romania. They each have their separate ninety-day limits. The time you spend in other countries does not affect how long you can spend in each of these countries without a visa.
You may need a visa or permit to stay longer, to study, work or travel for business.
