Applying for ILR after 3 years : But extension of the dependents?

Hello,

I am planning to apply for ILR in November 2025. I moved to the UK with my spouse and my two daughters, who are now 8-9 years old. I have some uncertainties before my ILR application:

Q1 - I understand that my spouse needs to complete 5 years before applying for ILR. However, after I obtain ILR, technically my GT visa is changing to settled status and will no longer active. Can my spouse still apply for a Global Talent Dependant Extension visa?

Q2 - My daughters are under 18. Some official sources mention that if at least one parent obtains ILR, the children can also apply for ILR. Is this correct?

I would really appreciate it if someone with experience could share their insights. This question has been asked before, but the answers are quite mixed. If those who have completed the process can provide answers here, this entry may serve as a useful reference for future applicants and I will mark this as solved.

Best regards.
