Does any of this apply if you are not a US citizen? As a non-US citizen, if I come to the US on holiday, what rights do I have, if any? [edited to add] Answering my own question, this PDF from the ACLU seems to have some answers: http://www.aclu.org/files/kyr/kyr_english_4.pdf http://www.aclu.org/files/kyr/kyr_english_4.pdf "Non-citizens who are in the United States—no matter what their immigration status—generally have the same constitutional rights as citizens when law enforcement officers stop, question, arrest, or search them or their homes. " However "Non-citizens at the border who are trying to enter the U.S. do not have all the same rights. "
