Laws barring Asians from legal immigration and naturalization in the United States began with the Chinese Exclusion Act of 1882 and expanded to include all other Asian groups by 1924. Beginning in World War II, U.S. lawmakers began to dismantle the Asian exclusion regime in response to growing international pressure and scrutiny of America’s racial policies and practices. The Japanese government sought to use the U.S. Asian exclusion laws to disrupt the Sino-American alliance of World War II, causing Washington officials to recognize these laws as a growing impediment to international diplomacy and the war effort. Later, the Soviet Union and other communist powers cited U.S. exclusion policies as evidence of American racial hypocrisy during the Cold War. A diverse group of actors championed the repeal of Asian exclusion laws over the 1940s and early 1950s. They included former American missionaries to Asia, U.S. and Asian state officials, and Asian and Asian American activists. The movement argued for repeal legislation as an inexpensive way for the United States to demonstrate goodwill, counter foreign criticism, and rehabilitate America’s international image as a liberal democracy. Drawing upon the timely language and logic of geopolitics, advocates lobbied Congressional lawmakers to pass legislation ending the racial exclusion of Asians from immigration and naturalization eligibility, in support of U.S. diplomatic and security interests abroad.
