(CNN) The US State Department rejected more than 37,000 visa applications in 2018 because of President Donald Trump's so-called "travel ban," according to new data released by the agency on Tuesday.

A State Department spokesperson confirmed that the applicants listed as "2017 E.O. on Immigration -- Subject to 2017 Executive Order on Immigration" were refused under Presidential Proclamation 9645 -- the third iteration of the President's controversial executive order that placed varying levels of restrictions on foreign nationals from eight countries: Chad, Iran, Libya, North Korea, Syria, Venezuela, Somalia and Yemen.

The Supreme Court in December 2017 allowed that version of the order to take full effect pending appeal after lower courts in two separate challenges had partially blocked it. The court upheld the ban in June 2018.

"Since December 8, 2017, the Department has fully implemented Presidential Proclamation 9645, consistent with the December 4, 2017 Supreme Court order," the State Department spokesperson said.

The number of visas rejected in 2018 represents a significant increase from the year prior, when less than 1,000 applications were turned down under the same category.
