“ Aliens living in this country are not necessarily sophisticated world travelers familiar with the present-day red tape that must be unwound to get from one country to another. Congress should at least indicate when, to whom, and for what the alien should apply. If, for example, the statute merely required an alien to report at a certain time and place to sign 'documents' collected by the American Department of State, the affirmative conduct demanded would at least be clear and specific. But the present statute, in my judgment, entangles aliens in a snare of vagueness from which few can escape. ”
