  End Warrantless Surveillance of Americans Act Amends the Foreign Intelligence Surveillance Act of 1978 (FISA) and the Intelligence Authorization Act for Fiscal Year 2015 to prohibit federal officers or employees from searching for a particular U.S. person (other than a corporation) in: (1) a collection of communications acquired under an authorization by the Attorney General and the Director of National Intelligence to target persons located outside the United States; or (2) nonpublic telephone or electronic communications, including communications in electronic storage, retained in an intelligence collection activity not authorized by court order, subpoena, or similar legal process that is reasonably anticipated to result in the acquisition of communications to or from a U.S. person without the consent of a party to the communication. Provides exceptions that allow searches of such communications for a particular U.S. person if: (1) the U.S. person is the subject of certain orders or emergency authorizations for electronic surveillance or physical search under FISA or the federal criminal code for the effective period of that order, (2) the life or safety of such U.S. person is threatened and the information is sought for the purpose of assisting that person, or (3) the U.S. person consents.
