CNN reports what we South Dakotans know from experience: Chinese investors love the EB-5 visa investment program. According to yesterday's report, Chinese immigrants took almost 6,900 EB-5 visas in 2013, 81% of the total issued. Compare that with the 16 EB-5 visas issued to Chinese immigrants in 2004, the year South Dakota started leaning on the program to support large dairy projects in East River.

Immigration lawyers tell CNN Canada's decision to end a similar immigration program based on poor payoff has already driven more immigrants to apply for EB-5 visas. Rich Chinese looking to buy their green cards get a great bargain from the U.S.:

"The cost is very reasonable in relation to other countries," [immigration lawyer David] Hirson said. Australia, for example, requires a $4.5 million investment -- nine times the minimum required in the U.S. [Sophia Yan, "Rich Chinese Overwhelm U.S. Visa Program," CNNMoney, 2014.03.25]

Readers know I'm not nearly as fond of the EB-5 visa investment program as the handful of South Dakota players who've profited from it without proper state oversight. But let me reach for a silver lining to the Chinese takeover of the EB-5 visa quota:

For rich Chinese, opportunities in America are attractive. A green card offers a way to send their children to college, escape heavy pollution and enjoy an improved quality of life, said Kate Kalmykov, an attorney with Greenberg Taurig. Plus, the EB-5 program is relatively cheap [Yan, 2014.03.25].

These Chinese investors want to escape pollution. So when they come here and see the spate of oil spills and pipeline ruptures driven in part by their home country's increasing thirst for North American oil, those EB-5 immigrants may join our fight to protect their new home from the predations of TransCanada's China-bound Keystone XL pipeline, keep the price of driving their new American Cadillacs down, and leave a billion barrels of dirty tar sands oil in the ground. Save West River, and save the planet: bring on more EB-5 investors!
