Not necessarily. While visas like the Skilled Worker Visa demand a job offer, several other options don't require immediate employment. For instance, the Ancestry Visa is accessible if you have a UK-born grandparent, the Investor Visa is available for substantial investments, and the Global Talent Visa is open to those excelling in fields like academia, arts, culture, or technology. Exploring these alternatives based on your qualifications and objectives can lead to UK migration without a specific job offer.
