Immigration is an important topic in the UK. People move there for work, study, family, tourism, and protection. Many use legal routes, such as the Skilled Worker Visa, with help from UK Visa Sponsorship Consultants. Others may qualify for routes like the Global Talent Visa UK based on their skills and experience. At the same time, some people enter through routes that are not approved by the UK immigration system. This has raised questions about legal vs illegal immigrants and how many people use each route. Here, we explain the available UK immigration statistics and what they really show.
Understanding Legal vs Illegal Immigrants in the UK Before looking at statistics, it is important to understand what the terms mean. Legal immigration and illegal entry are not always measured in the same way. What Does Legal Immigration Mean? Legal immigration means entering or staying in the UK with valid permission. People can use different visa routes based on why they want to come to the country. Common legal routes include: 1/4
Work visas. Student visas. Family visas. Visitor visas. Global Talent Visas. Skilled Worker Visas. Humanitarian routes. Other approved immigration routes. People who enter through these routes must follow the conditions of their visa. For example, a person on a work visa may need to work in an eligible job. A student must follow the rules of their Student Visa. A visitor usually cannot work or live in the UK permanently. The Home Office publishes regular statistics about the UK’s immigration system. These statistics cover visas, work, study, family routes, settlement, citizenship, asylum, detention, and returns. What Does Illegal Immigration Mean? The term “illegal immigration” is often used to describe people who enter or stay in a country without the required immigration permission. The UK government often uses the term illegal entry routes in its official statistics. This refers to people who are detected entering the UK through routes that are not approved. It is important to understand that entering through an illegal route and having no legal status are not always the same thing. For example, a person may enter the UK through an illegal route and then claim asylum. If their claim is successful, they may later receive legal permission to stay. Because of this, immigration statistics need to be read carefully when discussing legal vs illegal immigrants.
Legal vs Illegal Immigrants: Can We Compare the Numbers? A direct comparison can be difficult because the statistics measure different things. Legal immigration figures may show the number of visas granted for work, study, family, or other reasons. Illegal entry figures mainly show people who are detected entering through unauthorized routes. The Home Office explains that not everyone who enters through an illegal route will be detected. The number of detected arrivals can also change because of border checks and enforcement activity. For this reason, detected illegal arrivals should not be treated as the total number of people who entered the UK illegally. This is an important point when looking at legal vs illegal immigrants statistics. The two types of data do not always measure the same thing.

Latest UK Statistics on Illegal Entry Routes According to the latest Home Office statistics, 43,806 people were detected arriving in the UK through illegal entry routes in the year ending March 2026. Small boat arrivals made up around 90% of these detected arrivals. The number of small boat arrivals was slightly higher than the previous year. However, it was still 14% lower than the peak recorded in 2022. These figures are important, but they do not show everyone who may have entered the UK without permission. The statistics only cover detected arrivals. Some people may enter without being detected. Therefore, the figures cannot be used to calculate the exact number of people living in the UK without legal status.
How Many People Come Through Legal Routes? Legal migration includes many different groups. Because of this, there is no single figure that represents everyone who enters the UK legally. People may come to the UK for: Work. Study. Family reasons. Short visits. Humanitarian protection. Other approved reasons. In the year ending March 2026, the UK issued 779,000 visas for non-visit purposes. These included visas for work, study, family, and humanitarian routes. The UK also issued 2.2 million Visitor visas during the same period. However, visitor visas should not be directly compared with illegal entry figures. Visitors usually come for short stays, while illegal entry figures record detected arrivals through specific unauthorized routes. This shows why it is important to understand what each statistic measures before making a comparison.
Summary The debate about legal vs illegal immigrants in the UK is often based on simple numbers. However, official data shows a more detailed picture. People come to the UK through legal routes for work, study, family, visits, and humanitarian reasons. At the same time, thousands of people are detected arriving through illegal entry routes each year. The latest Home Office data recorded 43,806 detected arrivals through illegal entry routes in the year ending March 2026. Around 90% arrived by small boat. However, this figure

does not represent everyone who entered the UK illegally or everyone currently living in the country without permission.
