I am bit confused by the requirements
You can apply once you’re eligible.If you’re applying as a parent or a partner with a family visa, the earliest you can apply is 28 days before you meet the requirements for time spent in the UK. Your application may be refused if you apply earlier.
My wife arrived on 14/02/2018. And she has being continuously living in UK up to now. Does she needs to wait for 28 days to apply for her settlement. Her visa expiring on 19/08/2023. She has not left UK. Can anybody help on this. Thank you
