CNN Money reports on the popularity of the EB-5 program with Chinese nationals and the possibility that backlogs could soon develop for people from that country. 80% of EB-5 green cards are now going to Chinese nationals. As long as the program doesn't fill up, that's not a problem, but if the overall demand increases and there are more applications than the annual 10,000 allotment, China could start to see the kind of backlogs they face in a number of other employment-based green card categories.
