Executive Order 12711
The Executive Order 12711 was issued by American president George H. W. Bush on 11 April 1990. It deferred deportation of Chinese nationals and their direct dependents who were in the US between 5 June 1989 and 11 April 1990, waived the 2-year home country residency requirement, and gave them employment authorization through 1 January 1994.
It was issued as part of the international backlash against the People's Republic of China (PRC) in response for its suppression of the Tiananmen Square protests of 1989 that occurred 4 June of that year. It was made permanent when the Chinese Student Protection Act was passed in 1992.
