I am a British citizen by naturalisation. My wife is eligible for ILR on the 18th of February 2024 (28 days before 5 years complete) and my daughter will soon be 4 year old in a few days from now, so, she follows my wife's current visa expiration date which is in September 2025. I would like to apply for ILR for my wife.
My previous employer (Tier 2 Sponsor company) went insolvent this year on the 23rd of August. Since then, I was not in a full-time employment, however, I was self employed (Uber delivery and professional freelance combined). Whilst I am STILL self-employed, I have now secured a full-time employment from 1st of November 2023.
Assuming the brief background above would help you all with the following questions

1) Since I was not in a full-time employment from th 23rd August until the 30th of October 2023. Would I be able to use my payslips from current -full-time employment from November 2023 till January 2024 (3 -months) to satisfy the salary threshold of £18600? Or it has to be 6 months?
2) Can I combine the income from self-employment ( Uber and professional freelance service) and current full-time employment? Please note that I have so far ONLY submitted the self-assessment for the last year. I will submit the self-assessment for this year next.
3) Is it a must that I submit the ILR application for my wife and child together or I can only apply for my wife at first and then after my child?
Please let me know if you require any further information. I sincerely look forward to receiving your expert informatio and suggestions.
Have a good day!
Thanks, and regards
Raheem
