The immigration act of 1965 ended the national origins quota system gave preference to relatives of u. s. citizens gave preference to people that had valuable job skills reduced total immigration to the u. s. by five percent

The correct answer is: ended the national origins quota.

Indeed, until then, American immigration laws restricted immigration from Africa and Asia and favored immigration from northern and western Europe over immigration from Eastern and Southern Europe. Many domestic and international activists were vehemently opposed to such policies that were considered as discrimination on the basis of national origin. President Lyndon B. Johnson signed the act at the site of the Statue of Liberty in 1965.
