1 day overstay
Posting for a friend. So her parents came over to help her as she recently gave birth.
Parents are allowed to stay for 90 days. Her partner was the one who booked their flights and it was just recently that they noticed the date of their flight back will be 91 days, which means they are overstaying for a dat. They tried to look for a rebooking but it was almost the price of a return ticket.
Would it be worth emailing immigration service saying that it was an honest mistake rather than not admitting and will definitely affect future visa request?
Any advice is greatly appreciated
