Explained: UK’s ‘learn English or leave’ rule and cut to post-study visa duration

Migrants entering the UK will face tougher visa requirements under a new immigration law presented in Parliament this week. The government’s proposals include stricter English language testing, reduced post-study work rights, and increased financial thresholds for students.The measures are part of a broader strategy aimed at overhauling the existing immigration system, which the UK government has described as “failed.” The Home Office states that the changes are designed to create a more “controlled, selective and fair” approach to legal migration.Stricter English requirements for migrantsOne of the most significant changes is the introduction of a mandatory A-level equivalent English requirement for certain visa routes. Applicants must now prove proficiency in speaking, listening, reading, and writing through a Secure English Language Test (SELT). As outlined in the bill, the test must be completed via a Home Office-approved provider, and verified results will be a core part of the visa application process.Home Secretary Shabana Mahmood said, “This country has always welcomed those who come to this country and contribute. But it is unacceptable for migrants to come here without learning our language, unable to contribute to our national life. If you come to this country, you must learn our language and play your part,” as quoted by the Home Office.Reduced post-study work period for international graduatesFrom January 2027, international graduates will be allowed only 18 months to secure a graduate-level job after completing their studies. This is a reduction from the current two-year post-study visa duration. The Home Office has cited data showing that many international graduates were not transitioning into appropriate employment, prompting the change.Increased financial requirements for student visasStarting in the 2025–2026 academic year, international students must demonstrate higher financial reserves to be eligible for a study visa. The government stated that this move aims to ensure a greater economic contribution from those entering on student routes.Rise in employer costs through ISCThe Immigration Skills Charge (ISC), paid by employers sponsoring foreign workers, will increase by 32%. This marks the first rise in ISC since 2017. The additional revenue will be reinvested in UK-based workforce training programmes, according to the Home Office.Expansion of high-skilled visa routesThe High Potential Individual (HPI) route will expand to include graduates from the top 100 international universities. The annual cap for this route will be raised from 2,000 to 4,000 applicants. Additionally, the Global Talent route will see an expanded list of eligible awards, particularly in architecture, design, and the creative arts.Student entrepreneurs will also be able to switch directly from student visas to the Innovator Founder route, allowing them to launch businesses in the UK without leaving the country.
