ICE has arrested West African women who had lived in New York for decades after summoning them to 26 Federal Plaza in Lower Manhattan, advocates say. Federal habeas corpus petitions filed over a two-week period describe cases involving a house cleaner, a certified nurse’s assistant, a hair braider and a home health aide.

Immigration judges had found the women would face danger in their home countries and granted them protection from deportation there. A recent U.S. Supreme Court order could leave them vulnerable to rapid removal to another country despite that protection.

Advocates fear the arrests may signal an effort by the Trump administration to expand third-country deportations. The Supreme Court is set to consider the issue later this year. Asked about the arrests, a Department of Homeland Security spokesperson defended third-country removals as a public safety measure.
