In October 1995, Congress adopted the Jerusalem Embassy Relocation Act, noting that Jerusalem is the capital of Israel and that the U.S. Embassy should be moved there from Tel Aviv no later than May 31, 1999.
The Act also included a stipulation allowing the President to issue a waiver every six months to keep the embassy in Tel Aviv if he determines such is necessary to protect the national security interests of the United States.
Since 1999, each President - Clinton, Bush and Obama - has used the waiver to suspend the relocation of the Embassy at six month intervals, a copy of which is presented below. President Obama renewed the waiver most recently, on June 1, 2016.
