I agree with commenters above who said this was mostly about # 6. It truly was in my opinion as well, and I also agree that the rest are - for the most part - common sense. HOWEVER.... some people are missing a key point here based on my observation. This was an excellent way for the USA to close down the gap for Russians and people of Belarus to get into the USA by simply buying their way in WITHOUT having to modify its OWN (US) immigration rules. Actually, a rather fascinating way by the US Government to achieve this by making the Caribbean CIB countries to change their own ways of processing applicants while having a direct impact of their own (US) immigration. While it is only one door closed out of many others, it is yet another door they managed to close with it. Here is what I mean:
The reason why Grenada has been a long-time favorite for people is because they were using it as a gateway to get into the USA. Because of the country's status / treaty with the USA of E-2 investor visa program, wealthy individuals from Russia and Belarus could simply outright buy a passport from Grenada, and as a Grenadian apply in the USA for the E-2 investor visa and move their business (and their family) there. Now that's done. Sure, you can say that they still have many-many ways to do it.... but they will be much more difficult and lengthy. I helped many people with this strategy and there are still MANY ways to do this but it is yet another door closed for easy access. Again, applauding the USA for making this happen without modifying their own program that would have cost the US Taxpayers a lot of money.
Bravo!
