LOL... As if China is really offering citizenship for them? They go to US becos China is not opening for them.
What China really wants to achieve is to retain their talent. With widespread racism against Asian and especially Chinese. US will be deprived from a important contribution of science from China immigrants.
Talent like Li Fei Fei will never contributed to American science in future. I can bet she is also considering going back to China since racist white man will beat her up for no reason... I can bet she is now planning to fed american with all false info while ship back all the tech and know how to China since American white are so racist to her.

Btw, maybe you want to claim another racist attack on Asian Chinese is again the work of black man, White are nice people and never racist. Worst of all, this white supremacist pig just proves he is a disgrace to all white neocon, showing how weak they are that he cant even beat and defeat a 76 years old woman.
