As many of you know, a similar pact (the "MOU" or memoradum of understanding) was negotiated between the U.S. and Cambodia several years ago, resulting in many young Cambodians deported to Cambodia. The stories of some of these folks are well documented in the film "Sentenced Home," which I would highly recommend if you haven't seen it already.
It will give you a good idea of what will probably happen with the Vietnamese community. A lot of people argue that we would just be deporting folks who are "illegal" but that paints a very distorted picture. Many came here legally but may not be citizens, or got caught up in the system as a young person.
There are many possible scenarios as to how someone could get deported, and after doing some reporting on the subject, the government is keeping pretty mum about details of who these potential folks are, where they live, and specifics on why they will be deported. I don't think anyone has been deported under this new agreement, but I imagine they will start soon.
I think it will be a story that will play out in the next few years.
Give it up to the student activists to speak their minds on this important issue that could, and likely will, affect many Asian Americans.
