Hispanics mostly just have to cross the US-Mexico border. Asians have to get across the Pacific somehow, usually through legal means with high barriers to entry, which is a great filter for the type of people that make it through to the US. Also because of the communist crackdown on the gentry, most of Chinese emigrants were the well-off people, whereas in most cases emigrants from other countries are usually the poorer or less-well off segment of their populations.
