In essence, if you are able to get a good amount of money, or if you have good relations with certain individuals in the ICC, you will not have any problems at all. I believe that this is what has been happening in the ICC at the moment, and I believe that is what has been occurring. The teams that are made up of foreign players are being given a really good amount of money in order to make their teams successful. It is also evident that they are trying to include the USA in the cricketing world, despite the fact that everybody knows that the USA is not a very interested country in cricket.
It is not just the United States. And in case of US, I am a bit more lenient, because their squad do have 3-4 players with American citizenship. That is not the case with teams like Oman, United Arab Emirates and Hong Kong. The entire squad is made of foreigners, which defeats the very purpose of forming a "national" team. How can you call a team that comprises 100% of citizens from Pakistan and India as the UAE team? Just because some of these players reside or work in the UAE temporarily, a UAE national team can't be formed from them.
