The nation’s only detention center for families is routinely holding children beyond the 20-day limit, including an Iranian-born “average American kid” who’s been locked up for 123 days and counting.

But in April, U.S. Immigration and Customs Enforcement officers arrested the family, who immigrated from Iran more than a decade ago, after U.S. Secretary of State Marco Rubio told immigration officers to revoke their permanent legal status. ICE separated the family, sending them to two different Texas detention centers.

For the past 123 days, the teen and his mother have lived in an immigrant detention facility in Dilley, where he and other detainees share their rooms with swarms of cockroaches, spiders and mosquitoes, he wrote in a sworn affidavit. Meanwhile, his father is at the South Texas ICE Processing Center in Pearsall.

The teen is one of at least 60 children who the Trump administration has held in the Dilley detention center for 100 days or more — far exceeding the 20-day limit for detaining immigrant children — according to a Texas Tribune analysis of federal government data.
