I went to the U.S. Embassy in Mexico City, and was promptly denied a visa. I asked why, and they said, “We can’t tell you why. It’s a secret.” So I was left stranded and classified forever under the Undesirable Aliens list. I asked once, “Do you ever get out of that list? Can I ever get out?” and they said, “No, no, no.” I said, “Even hell has its limits. Even in hell you are promised that one day everybody will go to purgatory or to heaven; hell is not forever. Surely, the denial of a visa is not forever.” They said, “No, no, you can come out with a visa.” How? “If you demonstrate your allegiance to the cause of anti-Communism.” I said, “Well, that is something I will never do just on the principle of it. I am not a Communist, but I will not go to that McCarthyite length.”
