I didn't know about the 30,000 Chinese who enter America annually illegally and then disappear. That reminds me of how they absorbed Tibet. Rather than cause an ugly international scene, they simply crossed the border over the course of a decade, assimilated, and then began positioning themselves in position of government trust via local elections. If your number is accurate, watch for congress to begin electing Chinese Reps from densely populated Chinese districts across the US. California and NY come to mind immediately.
