From 1st December 2020, Tier 2 ICT visa holders can apply to switch within the UK into the Skilled Worker category. This then enables the visa holder to be on a track to indefinite leave to remain after 5 years as a Skilled Worker.
Additionally, the 12 month cooling period is also being removed.
Switching your visa will give you more flexibility with your employer, better opportunities and a pathway to ILR.
