Immigration and Visas: National Security

The UK operates a robust and effective visa system, which is an important part of securing the UK border and a vital tool for the UK in reducing illegal immigration, tackling organised crime and protecting national security. A requirement to obtain a visa prior to travelling to the UK means that we can assess whether an individual is a genuine visitor to the UK and will comply with the Immigration Rules on arrival. It allows us to intervene and, where necessary, refuse a visa before the individual travels to the UK.

The UK visa system, including the Visa National List, is kept under regular review. Decisions on which countries are required to apply for a visa (known as “visa national” countries) and which are not required to apply for a visa (known as “non-visa national” countries) are taken on the basis of a range of factors including security, compliance and returns arrangements.
