Initially, only 1,000 Hmong people were evacuated to the US. In May 1976, another 11,000 Hmong were allowed to enter the United States. By 1978 some 30,000 Hmong had immigrated to the US and by 1998, there were 200,000 Hmong living in the US. This first wave was made up primarily of men directly associated with General Vang Pao's Secret Army, which had been aligned with US war efforts during the Vietnam War. Vang Pao's Secret Army, which was subsidized by the US Central Intelligence Agency, fought mostly along the Ho Chi Minh Trail, where his forces sought to disrupt North Vietnamese weapons supply efforts to the communist Viet Cong rebel forces in South Vietnam. Ethnic Laotian and Hmong veterans, and their families, led by Colonel Wangyee Vang formed the Lao Veterans of America in the aftermath of the war to help refugees in the camps in Thailand and to help former veterans and their families in the United States, especially with family reunification and resettlement issues.
