UK Citizens travelling to the EU/Schengen Area after Brexit

UK NATIONALS LIVING IN CROATIA WITH RESIDENCE RIGHTS UNDER THE EU-UK WITHDRAWAL AGREEMENT
 
Traveling to Croatia: you will need a passport and a Croatian residence card. The same rules apply to your non-EU family members who are covered by the EU-UK Withdrawal Agreement.
 
Travel to another Schengen Member state: UK national Withdrawal Agreement beneficiaries travelling from Croatia to another Schengen Member state fall under the "visa free short stay rule" meaning they can travel visa free for a maximum of 90 days within a 180-day period. In addition, in line with Schengen rules, any non-EU national legally resident in a Schengen Member state, whether subject to a visa obligation or not, must have a residence document and a valid travel document for travel to another Schengen Member state for a short stay. You will therefore need a Croatian residence card, as well as your passport when you travel to another Schengen Member state.
 
Non-EU Family members travelling to another EU/Schengen Member state:

When travelling to the following EU and Schengen Member states: Austria, Belgium, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden and Switzerland, the residence document issued to your family members by one of these countries will allow them to benefit from a visa exemption for short stays, i.e. up to 90 days in any 180 day period.
 
The residence document issued to your non-EU family member by one of the above EU and Schengen member states will also allow them to benefit from a visa exemption when travelling to Bulgaria, Cyprus or Romania for short stays. However, if your EU country of residence is Bulgaria, Cyprus or Romania, the residence document issued to your family members does not exempt them from a visa for travel to the Schengen Member states.
 
UK NATIONALS WITHOUT ANY STATUS UNDER THE EU-UK WITHDRAWAL AGREEMENT
 
When travelling to the Schengen Member states for short stays, you are not required to have a short-stay visa (visa type C) when crossing the external borders, if your intended stay is up to a maximum of 90 days within a 180-day period. However, border guards will stamp your passport on entry to and exit from the Schengen area to ensure you respect this 90-day limitation.
 
If you are planning to carry out a paid activity during your stay in the Schengen Member state, you may have to apply for a short-stay visa (visa type C). Please check with the relevant consular authorities in the Schengen Member state you are travelling to for more information. Your non-EU family members may need a visa to enter Croatia and other EU/Schengen Member states, depending on their nationality. Check the Visa requirements overview and read about the visa issuance procedure if they need one.
