The first thing for me to say is that a very large number of people who were resettled, were resettled over a very long period of time, from 1979 to 1995. It didn't all start at once in the first year.
There was a special regulatory class created, called the Indochinese designated class, that set out criteria for the processing of Indochinese refugees, which, at the beginning, simply required that the applicant be a citizen of one of the affected countries, who had left that country after a certain date and who was presently in the region, in Southeast Asia, under the care of the international community.
Over time, it was recognized that such very general criteria were in fact encouraging more people to leave Vietnam, people who in fact were not at risk. As a result, the international community agreed on what was called the comprehensive plan of action, which mandated UNHCR to make individual refugee status determinations for all Indochinese refugees. Countries like Canada agreed to only resettle persons who were recognized by UNHCR as refugees. So there was a change to our approach. That would have been about 1989 when that change happened.
