Welcome to immigrationboards.com!
You likely also have to apply from outside the UK for the innovator visa.How long you can stay
You can stay for 3 years if you:
come to the UK on an Innovator visa
switch to this visa from another visa
You can apply to extend for another 3 years when your visa is due to expire. There’s no limit on the number of times you can extend.
You may be able to apply for settlement (known as ‘indefinite leave to remain’) once you’ve been in the UK for 5 years.
There is no shortcut route to ILR. You require 5 year residence.5 year is little challenging as we will have to make all the investments for visa / IHS/ etc and this will be twice for innovation visa
