While the U.S. ambassador reassured the Japanese government, Roosevelt summoned the mayor and school administration of San Francisco to the White House in February 1907 and convinced them to repeal the segregation order and promised that the federal government would tackle the immigration issue itself. On February 24, the gentlemen`s agreement was reached with Japan in the form of a Japanese note in which it was agreed to deny passports to workers who wanted to enter the United States and to recognize the right of the United States to exclude Japanese immigrants holding passports originally issued to other countries. This was followed by the formal withdrawal of the order of the San Francisco School Board on March 13, 1907. A final Japanese note of 18 February 1908 made the gentlemen`s agreement fully effective. The agreement was replaced by the 1924 law excluding immigration. The United States stopped the Bracero program in 1964, and Cesar Chavez and United Farm Workers earned a 40 percent wage increase for California grape pickers in 1966, in part because Mexican workers were unavailable. However, by the early 1970s, illegal immigration from Mexico had increased, and the House of Representatives authorized employer sanctions imposing fines on U.S. employers who had knowingly hired illegal foreign workers. However, at the request of the peasants, the Senate refused to give its consent. Instead, Presidents Gerald Ford and Jimmy Carter appointed commissions to investigate the causes and consequences of illegal immigration. In 1981, the Immigration and Refuge Commission (IPRSC) concluded that immigration took place in the United States.
