Yes, most migration routes to the UK require a valid job offer. The Skilled Worker visa and Health and Care Worker visa are job-offer dependent, as they require sponsorship from a licensed UK employer and a Certificate of Sponsorship. However, some visas allow migration without a job offer. The Global Talent visa permits highly skilled individuals to apply with an endorsement in their field. Similarly, the Innovator Founder visa requires a business plan rather than a job offer. While job offers are essential for most applicants, alternative pathways exist for exceptional talent and entrepreneurs.
