What are the chances or percentage likelihood of getting work visa sponsorship and staying beyond 4-5 years in UK for a Master's?

It is possible to secure work visa sponsorship in the UK after your master's, especially with your 10 years of experience. However, the likelihood depends on several factors:

- You must get a job offer from a UK employer approved to sponsor visas.
- The job must meet the Skilled Worker Visa criteria: eligible occupation (typically graduate level or above) and minimum salary (currently £41,700/year or the occupation’s going rate, whichever is higher; subject to change).
- Strong work experience improves your chances, but success depends on the UK job market and employer demand in your field.

If you secure sponsorship and maintain continuous employment, you may be eligible for permanent residency (Indefinite Leave to Remain) after 5 years.
