Backdrop of mexican immigrants in to united states of America

The United States developed and grew from thirteen colonies to fifty states and has, gone through so many discoveries, explorations and settlements. The Immigration has played an important role in American history, and has the most open immigration policy in the world. The extensive explorations in US were from many lands like Spain, Great Britain, Holland and Sweden. In 1875 it was declared the regulation of immigration was a federal responsibility. After that there was series of Immigration acts and programmes were implemented. The national-origins quota system passed of 1921, Bracero programme 1942, McCarran–Walter Act of 1952, The immigration act of 1973, Immigration Reform and Control Act (IRCA ) of 1986, 1990 Immigration Act, Illegal Immigrant Reform and Immigrant Responsibility Act (IIRIRA) of1996, the Border Protection, Anti-terrorism, and Illegal Immigration Control Act of 2005, Comprehensive Immigration Reform Act of 2006 (CIRA), and the Comprehensive Immigration Reform Act of 2007. The legislations passed from time to time by US government has controlled the level of migration into the country from Mexico both legal and illegal. Donald Trump for keeping a campaign promise, signed an executive order on January 2017 which immediately but temporarily banned citizens from seven countries – Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen – from entering the U.S. The Mexicans are the largest single group of those living illegally in the country. During his first 100 days in office, President Trump has taken a sweeping set of actions on immigration, ranging from imposing a travel ban to cutting refugee admissions and travel ban. This policy affects mainly on Mexicans in US. The Chief Justice John Roberts opined positively and he made justification for Trum’s decision and has withstood court scrutiny. But he also declared the endorsement of decision has constitutional ground. But the sudden policy shift triggered chaos at international terminals in U.S. airports nationwide, and several immigrant-rights groups sued on behalf of refugees and other migrants.
