A European Union official, who led talks Tuesday between Iran and a group of five world powers, said participants were determined to keep alive the 2015 nuclear deal, which limited Iran`s nuclear program in exchange for sanctions. However, the results of the field visits should take three months, according to a diplomat familiar with the case, so that « it could be a problem with the Iranians » if something undclared and nuclear is found. The Judeo-American community was divided over the agreement. On August 19, 2015, the leaders of the Jewish Reform Movement, the largest Jewish denomination in the United States, made a lengthy public statement expressing a neutral position.   The declaration signed by the leaders of the Union for the Reform of Judaism, the Central Conference of American Rabbis, the Center for Religious Action on The Reform of Judaism and the Association of Zionist Reform of America reflected what Rabbi Rick Jacobs, president of the URJ, described as a « deep division within the movement. »  On August 20, 2015, a group of 26 local Jewish elected officials present and foreign published a full-page advertisement in the New York Times containing a statement supporting the agreement; The signatories included three former presidents of the Conference of Presidents of Major American Jewish Organizations, as well as former AIPAC Executive Director Tom Dine.  On August 17, 2015, a group of 340 rabbis, organized by Ameinu, wrote an open letter to Congress supporting the agreement: « We fully support this historic nuclear agreement with many other Jewish leaders. »  The signatories were mostly reforming rabbis, but at least 50 rabbis of the conservative movement and at least one Orthodox rabbi. Among the chief rabbis who signed the letter were Sharon Brous, Burton Visotzky, Nina Beth Cardin, Lawrence Kushner, Sharon Kleinbaum and Amy Eilberg.  In a separate letter published on 27 August, 11 former Jewish democratic members of Congress asked for their support for the agreement; The letter noted the pro-Israel certification of the signatories and the agreement « ends the imminent threat of a nuclear Iran, » while refusing to « put Iran back on the path of developing a nuclear weapon within two to three months. » Signatories included former Senator Carl Levin and former representatives Barney Frank, Mel Levine, Steve Rothman and Robert Wexler.  On July 19, 2015, the Department of Foreign Affairs formally forwarded the JCPOA, its annexes and related materials to Congress.  These documents contained the UNclassified audit evaluation report of the JCPOA and the classified information community appendix to the evaluation report.  The 60-day review period began the next day, July 20, and ended on September 17.  Senator Ted Cruz introduced a resolution to delay the audit period and argued that the 60-day review by Congress under the legislation should not begin until the Senate has received a copy of all Iran-IAEA bilateral documents.
This resolution was not adopted.   Finally, a resolution of disapproval was brought to the Senate, but failed. A motion for a resolution was submitted to the Assembly, but it also failed. As a result, the agreement came into force following congressional review.  Gary Sick states that in the history of the NPT, no country other than Iran has voluntarily agreed to submit its nuclear activities in such an extraordinary manner.  In 2018, IAEA inspectors spent a total of 3,000 calendar days in Iran, installed manipulative seals and collected surveillance cameras, measurement data and documents for further analysis.
