(JTA) – The Trump administration will formally move the U.S. Embassy to Jerusalem from Tel Aviv in May to coincide with Israel’s 70th anniversary. “We’re planning to open the new U.S. Embassy to Israel in Jerusalem in May,” a State Department spokesman told JTA in an email. “The embassy opening will coincide with Israel’s 70th anniversary.” May 14 would mark 70 years since Israel’s establishment. The spokesman said the embassy would be located in a southern Jerusalem neighborhood on the side that Israel held before 1967 but running along the seam of what was then the border.

“The embassy will initially be located in Arnona, on a compound that currently houses the consular operations of Consulate General Jerusalem,” he said.

Building a new embassy will take at least three years, and the spokesman suggested that at least for now, much of the daily operation of the embassy would remain in Tel Aviv. “At least initially, it will consist of the Ambassador and a small team,” the spokesman said of the Jerusalem operation.

Trump administration officials had said previously that the embassy move would take place in 2019. President Donald Trump has heralded his Dec. 6 recognition of Jerusalem as Israel’s capital as one of the highlights of his administration. He earned lengthy applause on Friday, Feb. 23 from the CPAC annual conservative conference in Washington when he mentioned the Jerusalem recognition.

Another source apprised of the move provided JTA with a timeline for the move: In the first phase, starting in May, Ambassador David Friedman and some staff will begin working out of the consular section. In the second phase, by the end of 2019, an annex on site will be constructed for a more permanent working space for the ambassador, staff and a classified processing site. The third phase, the site selection and construction of a new embassy, will take up to nine years.
