Even though President Donald Trump’s travel ban has run afoul of the courts, the number of visas issued to people from six majority-Muslim countries targeted by the executive order appears to be slowing down dramatically.

Separately, refugee resettlement in the U.S. from February through May has also plummeted, according to CQ Roll Call’s review of data released by the State Department.

While the trend concerns immigration and refugee advocates, the drop suggests the administration may be able to slow down the flow of people from countries linked to terrorism without a travel ban that judges say discriminates on the basis of religion.

The Trump administration declined to answer questions about the visa trends, making it unclear whether the State Department is granting fewer applications or whether fewer people from the targeted countries are applying.

“I would imagine it’s both,” Justin Cox, a staff attorney at the National Immigration Law Center, said about possible reasons for the downturn. “If I were from one of those countries, I certainly wouldn’t feel welcome in the United States right now.”
