Is work visa sponsorship available for the roles you mentioned, and are these roles eligible to be converted to work visas in UK?

Yes, work visa sponsorship is available for roles that meet the UK's Skilled Worker visa requirements, and these roles can be converted to a work visa if eligible.

To qualify, you must have:
- An eligible occupation (listed under the UK's Standard Occupational Classification codes)
- A confirmed job offer from a UK employer approved by the Home Office
- A salary meeting the minimum threshold (currently £41,700/year or the occupation’s 'going rate', whichever is higher; subject to change)

If these conditions are met, your role is eligible for sponsorship and work visa conversion.
