If you travel to the UK with the purpose of transit, business trip, tourism and family visits for the period up to 6 months, you don’t need to apply for a UK Visitor Visa at least till December 31, 2021. It doesn’t mean that to pass the boarder control in the UK will be as easy as it was before Brexit. Now it is obligatory to prepare a few documents to show that :

• you’re visiting for tourism, business trip, family visit, transit
• you’re able to support yourself and your dependents during your trip (or have funding from someone else to support you)
• you’ve arranged accommodation for your stay
• you’re able to pay for your return or onward journey (or have funding from someone else)
• you’ll leave the UK at the end of your visit
• In case if a EU citizen travelling to the UK is under 18 years and he/she is travelling alone, it is obligatory to show:
  - parental or guardian contact details and consent for you to travel to the UK
  - the name, date of birth, address and relationship to you of the person you’re staying with their consent for you to stay with the person named in the letter
• If you’re not staying with a close relative Your parent or guardian must tell the relevant local authority about your visit if you’re both of the following:
  - under 16 (or under 18 if you have a disability)
  - going to be looked after for more than 28 days by someone who is not a close relative (called ‘private foster care’). You should bring a reply from the local authority if you have one.
