'the answer is in what happened in south Vietnam. They didn't take many with them to the US.'
From Wikipedia..so it must be true....
The Fall of Saigon on April 30, 1975—which ended the Vietnam War—prompted the first large-scale wave of immigration from Vietnam. Many people who had close ties with the Americans or with the then Republic of Vietnam government feared promised communist reprisals. So, 125,000 of them left Vietnam during the spring of 1975. This group was generally highly-skilled and educated. They were airlifted by the U.S. government to bases in the Philippines and Guam, and were subsequently transferred to various refugee centers in the United States.
Probably should have taken more....and I understand they did in subsequent years...many more...
