I share your concerns that sooner or later the number of alien workers are going to be limited. But this is nothing new. As the economy goes up and down, so does the number of H-1bs.
The more important question is, what's going to happen to people who are already here with H-1s and who have expressed interest in a permanent resident status. Historically, Republican Governments have always been anti-immigrant. They were able to show that in subtle ways in the past. Post 9/11, they are more blatant. Remember that justice department wanted to shut down immigration immediately after 9/11? I agree that one more attack and we can pack our bags. Like you all, i also pray that there be no more such stupid attacks for more than one reason. Rightwing groups are active throughout the world after 9/11.
Since we all do not have voting rights, the only way to seek political support is to contribute to election campaign of people whom we believe will be our voice in congress. We are all fairly well to do (financially) and it's about time we start thinking about doing something, as a group.
