Thanks @Shreeniwas_Iyer for the explanation, one quick question. If i apply for skilled worker visa and enter on that visa to the UK, so after 6 months i get the tech nation endorsement approved and i switch to the global talent visa, the time incurring for the ILR will be 3 years after the 6 months i am in the UK or it will incur from the date i enter UK on the skilled worker visa? so the total time would be 3 years or 3 years and 6 months to be considered for IRL? Please advise.
