Asking about stage 2 and ILR

Hi folks,

I would like to ask about the global talent visa (endorsed fund).

  1. After 3 years, in the case do not have a job offer to apply for ILR because my current contract might finish 2 months before, can I extend it to another 2 years?

  2. I switch from a student visa, and my dependents can apply for ILR because they have been living here for 5 years.
