As I've already pointed out in my previous posts, if they become citizens then there is nothing wrong with it (Barring direct appointees from the Gov -not kids-, the staff includes both sets of people Locals/foreigners, locals could be from any origin and it's fine too).
Spending is debatable and unexplored territory for obvious reasons but it shouldn't be much different from the existing setup, which is pouring money into the domestic grassroots infrastructure of cricket.
No one in their right minds would oppose the inclusion of naturalized citizens in any of the national teams. As a matter of fact, I am a big supporter of teams such as Netherlands and Namibia, whose playing XI consist of several individuals who recently received the passport of these respective countries (such as Ruben Trumpelmann and Brandon Glover). My issue is that ICC treats countries such as Netherlands (which has a cricketing history of more than 200 years and dozens of cricket clubs) and Norway (which doesn't have a single citizen in it's playing XI) in the same category.
