HK is one of the hardest places to enter during the pandemic. Formerly, the rule was that if you were from a Group "A" risk country (which was a very large list of countries), you cannot enter Hong Kong if you are not a HK resident without "washing out" for 21 days outside a Group A country. People from Group B-risk countries are allowed in if they have only been in the Group B countries for at least 14 days. But now 8 countries like the US, Canada, France, Australia and the UK are in an even higher category which is completely banned from entry, even for HK residents, unless the person has met the dual rules of having spent 21 days outside those countries AND also 14 days in a Group B country. So in other words, if someone is coming from the US, even if they live in HK, they must spend 21 days outside one of those countries, and also must go to a country like Mexico (or Thailand) and spend 14 days there "washing out" before they are allowed to come to HK, where like all arrivals, they will then have to spend 21 days in a self-paid hotel room quarantine where they must undergo a total of 8 RT-PCR tests during their quarantine. Essentially an American or a Brit or an Australian has to spend a total of 42 days between the washout period and the quarantine period from the time they leave their country until the moment they are free to walk the streets of Hong Kong. Makes Thailand's AQ and Sandbox programs look like a breeze. This is why I have little patience for people who criticize Thailand's minor restrictions. I'm always like, do you realize it would take you 42 days in order to visit HK? So don't complain about 7 days or about a Day 1 and Day 5 test.
