I'm basing my numbers on actual immigration rates. You can see the numbers here: http://www.uscis.gov/graphics/shared/stati.../data/dslpr.htm
In 2003 the US allowed in 40,000 from China. By 2007 that number was 70,000. For India it was an increase from 50,000 to 85,000. Overall Asian immigration increased from 243,000 in 2003 to 400,000 in 2005. By 2010 the United States will be allowing in over 100,000 Chinese per year.
Profile legal resident that allowed in:
Chinese Increae 75%
Indian increase 70%
Asian overall increase 65%
It will take many decades for Latinos to outnumber non-Latinos, and the US is increasingly opening its doors to immigration from China, India, and parts of the Far East.
In the same year south american legal resident granted from 55,000 to 103,000 = 87%.
That is without counting millions number of illegal resident from hispanic countries every year entering US.
