Plenty of other minority groups have faced discrimination at some point or other in the United States. A lot of anti-immigrant legislation passed in the late 1800s was focused on both Chinese and Japanese laborers on the pacific coast. Kornel Chang's Pacific Connections: The Making of the U.S.-Canadian Borderlands illustrates that in the last decades of the 1800s many white labor unions formed to protect white labor against the perceived threat of Asian immigration. Filipinos also faced discrimination when coming to America in the early 1900s, their lives in the U.S. were often complicated because of their ambiguously defined status as "subjects" but not citizens of the United States. More recently, an obvious example would be imprisonment of Japanese-Americans during World War II.

White immigrants from Eastern and Southern Europe faced discrimination and were often arrested for being either Catholic or Socialist. Organized labor was early on considered "un-american", and throughout the first decades of the twentieth century European immigrants were arrested and sometimes deported for their ties to unions and organized labor. (In connection with the above discussion, it is ironic that labor organizing could be used to discriminate against foreign labor but also defend the rights of white male labor). The Palmer Raids in 1919 and sedition and immigration acts passed in 1918 were attempts to deport Southern and Eastern European immigrants linked in some degree or another to organized labor. By the end of World War II, most European immigrants had been incorporated into suburban white power structures and were no longer viewed as being non-white.

Another great book to look at would be Mai Ngai's Impossible Subjects : Illegal Aliens and the Making of Modern America. In her book she traces the creation of U.S. immigration legislation from the 1910s and the Johnson-Reed Act (passed in 1924) up to the Hart-Cellar Act in 1965. She touches a lot on the issue of Asian immigration which was the reason for much of the early U.S. immigration laws, but by the post-1945 period Latin American, especially Mexican immigration, became a much larger concern for U.S. policy makers. One big incident occurred in 1943 is called the Zoot Suit Riots, in which white servicemen attacked young Mexican-Americans wearing suits using a large amount of fabric, during a time of rationing for the war. Latin American immigrants have also been the focus of immigration debates for decades now, and I am no expert on that so maybe someone else could shed light on more recent immigration debates.

Most minority and immigrant groups in the United States have faced discrimination at one time or another both structurally and culturally. Native Americans also have obviously faced discrimination. I must admit I know little about U.S. native policies and reservation laws, but native americans have fought to have their voices heard culturally and politically, a prominent example being when a group of Lakota occupied the town of Wounded Knee in 1973 to protest the U.S. government's failure to uphold treaties with native nations.

The civil rights movement sparked and brought to the national stage many minority groups fighting and protesting for their rights.
