None. It is one of the requirements of the U.S. Constitution that the U.S. President be born in the U.S. (See the fourth paragraph of Article II, Section 1 of the Constitution.) Here's a link to the transcript of the Constitution on the National Archives website: http://www.archives.gov/national-archives-experience/charters/constitution_transcript.html "No Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President;..." Plus, all the birthplaces of the (to date) 43 presidents are known. See this list: http://www.infoplease.com/ipa/A0194030.html Mar 22 06, 11:17 AM

There is long-standing speculation that Chester Alan Arthur, whose official birthplace is Fairfield Vermont, was actually born across the border in Quebec. Mar 22 06, 11:28 AM
