there is the tale of a french game developer who did what you said, and the IRS still managed to froze his foreign bank account.
basically, he gave up his US residency. Moved back to his native france, joined a game company that turned huge. on the IPO(?) the IRS got france to hold his assets because he was evading taxes, by renouncing the residency.
..i'm trying to find the history or the names. but failing, i'm sure someone here can help...
But if you're going to abandon your green card, you need to do it before the eight year because doing it after that makes you subject to the exit tax where abandoning your green card requires giving up a nice chuck of your net worth.
