@Joe *******
you cannot change a tourist visa into an ED visa in country at present but maybe by the time my tourist visa ends the quarantine will have dropped so then can do a visa run. At this moment in time my plan is now to fly to Thailand on 26th December and have 3 months there. Fly back to the U.K. for a month or 6 weeks and then fly back to Thailand with an ED visa and start my course because although I was meant to start on 18th January they are allowing me to change the start date to whenever suits
