I’m planning on flying from 🇬🇧 on the 15th January, when would be the best time to apply for COE as I’ve seen that it take 3 working days for embassy to process the application, then have 15days to book ASQ & flights, then resent back and another 3 days for final approve, then rt-pcr test 72hrs before: Is there a time limit on this or can you sit on the COE for a while? Anyone from England done this? Might be a stupid question but good to hear people experiences. Thank In advance
