I think pg's point of investors accreditation system is that it's not the government you have to cheat, but the group of pre-selected investors. (I'd imagine something similar to professional guilds... you have to be recognized by peers to be in part of the investor group of deciding who can get invested with this visa, for example).
The obstacle I see is that the stake of having authority to say who can get visas for work is very high these days (not like student visas); lots of people are seeking ways to get working visas desperately. So there would be lots of political frictions to introduce investor's accreditation system.
But yet, if politicians are convinced that this is crucial to revitalize the economy (which is probably one of the highest priority items), much of such muddling of power games may be avoided.
