I yield myself 5 minutes more. They come to the United States. At the same time they get a visa to Mexico. Then on this passport they also have a visa to Cuba or some other country. They have that visa to the United States and the visa to Mexico and the visa to Cuba. then these friendly enemies. or whatever you may want to call them. come over here. and they have their conference. and they say. "We are going to Mexico. and we are going to hold a conference there." and that is where they make the ball. and they will come back here to shoot it. So they are admitted into Mexico under the visa they have. and also they have a right to go to Cuba and come back to the United States. and they go and arrange all of their work. and they come back from Cuba or Mexico to the United States. Under this proposed bill they cannot do that. That is what we are trying to prevent. and we are trying to prevent our own citizens who are doing the same kind of work.
