I’m a little confused about the 3-year guideline.
After 3 years in the UK on a Talent visa, do I need to extend it at least for a year before applying for ILR, or can we apply for ILR before the 3-year term ends?
If there is any official link you could provide, that would be super helpful.
If you have been endorsed under Global Talent - Talent root, not Global Talent - Promise, then you can apply for ILR after 3 years.

However you will still have to wait for 5 years in the UK to be qualified for citizenship.
