I’m in the same boat as you. Haven’t seen DS for 18 months. Unfortunately, we’re going to have to wait a while longer. The US is still refusing entry to British citizens if you have been in the UK in the 14 days before travel. There is the odd exemption, eg if your spouse or you have a child under 21 who is a US citizen and you are going to be with them but just visiting family is still a no-no. This is a problem with UK guidance - it’s all very well having an amber list of countries but it doesn’t tell you that many of those countries won’t let you in. DD is in Thailand, which is on the amber list but borders are closed and not likely to reopen before October, if then, as hardly anyone in Thailand has been vaccinated.
