I had a query related to UK visitor visa extension. My mother in law got UK visitor visa from 5th April to 4th October 2019. She traveled to UK on 6th April and traveled back to India on 18th May (she stayed in UK for 44 days) Now she again traveled back on 1st July and her planned return date is 3rd Oct (95 days planned stay). So her overall stay is four and half months in UK.
Reason for her travelling now and extension is - currently my wife is expecting and her delivery date is 23rd September. So, my mother in law wants to extend her stay for around 2 months.
Is it possible? If yes then please suggest the procedure.
