The agents will be meaning, you come in on a visa exempt, you have to change that to a o visa which will give you another 90 days then change that to a non o based on retirement, my understanding is that is the process you have to go through,
Would also like to travel to the uk but would like to find out which countries I could stop in for 10 days before I reach the uk to avoid any type of quarantine, British citizen, double jabbed with Pfizer, thanks,
