First, OPT is not a visa. Optional Practical Training participants are mostly F-1 visa holders. Per IRS rules[1], the social security tax exemption "does not apply to F-1,J-1,M-1, or Q-1/Q-2 nonimmigrants who become resident aliens." And per IRS rules [2], you are considered a resident aliens if you pass the Substantial Presence Test [3], which states, "31 days during the current year, and 183 days during the 3-year period that includes the current year and the 2 years immediately before that." Now how many students can get an OPT job and still fail this test?

The US immigration policy is not perfect and has holes. But attracting foreign talents to stay and work in the US is the baby, not the bath water.

The timing of Uber leaving China - Aug 2016 - coincided suspiciously with the Chinese government legalizing ridesharing - announced in July 2016 to kick in November 2016. Isn’t that interesting? Per HBR:

> Under the new regulations, the data collected by Uber would come under the purview of the government. There would be no more subsidies. Market prices would prevail, the regulations state, “except when municipal government officials believe it is necessary to implement government-guided pricing.” According to Xinhua, ride-hailing companies would be urged to merge with taxi companies. (Many of those also happen to be owned by the local governments.) Uber would have to get both provincial and national regulatory approval for its activities anywhere in China. Online and offline services would be regulated separately.

> Moreover, foreign companies like Uber would be subject to even more regulation than their competitors.

This has always been the MO of Chinese government: blackmail though selective enforcement of broad-stroke laws. They tell you to leave without having to mouth it.

> Two pieces of legislation are of particular concern to governments — the 2017 National Intelligence Law and the 2014 Counter-Espionage Law. Article 7 of the first law states that "any organization or citizen shall support, assist and cooperate with the state intelligence work in accordance with the law," adding that the the state "protects" any individual and organization that aids it.

> During WWII, he was involved in the Manhattan Project, which ultimately led to the successful development of the first atomic bomb in America.

> During the Second Red Scare, in the 1950s, the US federal government accused him of communist sympathies. In 1950, despite protests by his colleagues, he was stripped of his security clearance. He decided to return to China...

> Upon his return, he helped lead the Chinese nuclear weapons program. This effort ultimately led to China's first successful atomic bomb test and hydrogen bomb test, making China the fifth nuclear weapons state, and achieving the fastest fission-to-fusion development in history.

> Qian was invited to visit the US ..., but he refused the invitation, having wanted a formal apology for his detention. In a reminiscence published in 2002, Marble stated that he believed Qian had "lost faith in the American government" but that he had "always had very warm feelings for the American people."
