Eight people from Myanmar, Laos, Vietnam, Cuba, Mexico and South Sudan were on a flight reportedly intended for South Sudan this week.

A federal judge has ruled that U.S. officials must retain custody and control of migrants apparently removed to South Sudan in case he orders their removals were unlawful.

Immigration attorneys have accused the Trump administration of deporting immigrants from Myanmar and Vietnam to South Sudan in violation of a court order, per a filing Tuesday that's requesting their "immediate return.

Lawyers for the immigrants, who aren’t from South Sudan, contend the deportations violate a court order after a previous attempt to send some people to Libya.

Immigration authorities refused to say what their final destinations would be, but said their home countries had refused to receive the migrants.
