A work visa in the UK allows non-UK citizens to work and reside in the country for a temporary period of time. There are a variety of work visas available, each with its own eligibility requirements and application process. The most common type of work visa is Tier 2, which is for skilled workers sponsored by a UK employer. In order to obtain a Tier 2 visa, the applicant must have a job offer from a UK employer and meet certain skill and salary requirements. Other work visas include Tier 5 for temporary workers, Tier 1 for highly skilled individuals, and the Youth Mobility Scheme for young people between the ages of 18 and 30. It is important to carefully review the requirements and restrictions for each visa before applying, as the process can be complex and time-consuming.
