I got my retirement extension in Feb, 1st 90day due in April, but I went back to UK on the 1st April urgently. I came back with my re entry in June and the IO changed the next 90day to September. Now I know your first 90 report has to be in person but I was wondering if the sep 90 is my first or second notification. If it's the 2nd then I can do it online?
