Immigrants, as troubling as they are to some people, are an integral part of what the American Dream is supposed to be. They're understandable to a considerable number of Americans.

In the United States, we want to believe we will never become a country of refugees.

The refugees are not only going to be a demand on the country's resources, but also the refugees raise the possibility that the countries that they're going to are themselves not as stable as the citizens would like, I think. We're all just one catastrophe away from ending up as a refugee, and we don't want to be reminded of that.

Refugees, especially in their early years, are still caught up in the experience that made them refugees. And they're much more melancholic. They're much more oriented towards the past and towards the country of origin. That can make the process of becoming a part of the new country much more fraught for them.

When I was growing up, I cared very little for the customs of my parents, the special things that we're supposed to do as Vietnamese people. But now that I am a parent, I go out of my way to make sure that my son goes to visit his grandparents and participates in customs like the Lunar New Year celebration.

Refugees have been displaced by war or natural disaster or political catastrophes, and they are much more threatening because they are reminders to people that all the comforts that we take for granted can be taken away in just a moment.

40, 50 years ago, Americans - the majority of Americans did not want to accept these Vietnamese refugees who they saw as completely foreign. Now there are new foreigners - Syrians and other people from the Middle East, people of Muslim backgrounds. And the sense among many Americans is, well, these people are completely different from us, and they're not like the Vietnamese who are much more assimilable. And I think that's very, very doubtful. I think that the majority of these new foreigners, if given the opportunity, will be able to assimilate and deal with American culture.
