"Untold Triumph" documentary film about WWII 1st & 2nd Filipino Infantry Regiments of U.S. Army at library - AnnArbor.com More than 150,000 Filipinos immigrated to the United States from the Philippines between 1906 and 1935, in search of the American Dream. Facing discrimination and hard times here in California and all along the west coast, thousands of Filipinos worked in agricultural fields, in the service industry, and in other low paying jobs. Even though they endured a racist pre-war climate and weren't even considered U.S. citizens, Filipinos in America rallied to join the American war effort after the bombing of Pearl Harbor. In 1942, an executive order was signed which allowed Filipinos to join the U.S. Army and form a volunteer all-Filipino unit.
