It was never easy for migrants to win asylum cases in U.S. immigration courts. But now, it’s nearly impossible.

Out of tens of thousands of migrants who have arrived at the southern border in recent months, just 117 have been granted protection by a judge. That’s according to the latest immigration court data released Thursday by the TRAC Immigration project at Syracuse University.

The U.S. asylum system has been upended by the Remain in Mexico program, also known as the Migrant Protection Protocols. More than 55,000 migrants have been told to wait in Mexico under the program, according to U.S. Customs and Border Protection. The court data released Thursday show that about 24,000 of their cases had been completed as of Nov. 19.

The success rate is less than 1%.
