In fact the link I posted estimated "22 million" Chinese "would likely come" - but to this you would have to add their spouses and children (and maybe their parents and siblings).
I mainly posted to give a grasp of how the HIGH the worldwide numbers really are and how CLUELESS Rand Paul is when (in his recent speech on idea of immigration reform) he said:
"If you wish to work, if you wish to live and work in America, then we will find a place for you."
To put it in perspective, present migration rate is just over a million and a half people a year, or about .4 percent. Demand at present is about 6x this, or what would be 2 percent immigration per year.
However, this is just at present. Those numbers are going to change. Thanks to Obama, America now has a long term deficit of about 600k people per year, about 40 percent of the present immigration rate.
If the people shortage increases while the immigration demand to the United States drops, it would be quite possible to see US total immigration demand be less than the present worker shortage (as we see in China, Japan and most of eastern Europe).
Paul might be wrong today, but he won’t be wrong for long.
