By MATTHEW LEE, AP Diplomatic WriterNEW YORK (AP) — The Trump administration has barred Iranian diplomats based in or visiting New York from shopping at wholesale club stores like Costco and purchasing luxury goods in the United States without specific permission from the State Department. The move is another step in the Trump administration’s crackdown on visas, including for leaders and diplomats seeking to serve as representatives at the United Nations. While world leaders are gathering this week for the high-profile annual meeting at the international body, the new U.S. restrictions permanently apply to any Iranian diplomats representing their country at the U.N. year-round. The Trump administration has already denied visas for Palestinian leader Mahmoud Abbas and his large delegation to attend the U.N. General Assembly. In addition to Iran, the administration also was considering restrictions to be imposed on delegations from Sudan, Zimbabwe and Brazil.
