A 53-year-old Indian-origin woman, Meenu Batra, was detained by Immigration and Customs Enforcement (ICE) in Texas last month.
Batra, a court interpreter, alleges she was held for 24 hours without food or water and denied medication for several days after her arrest.
She was arrested on March 17 at Harlingen International Airport while traveling to Milwaukee for work and remains in custody at the El Valle Detention Centre in Raymondville.
Batra claims officers made her pose for photographs while handcuffed and that the images were intended for social media.
Her detention has sparked concerns over due process, with her lawyers seeking her release.
Batra, who has lived in the US for over 35 years, is a single mother to four children, including a son who recently enlisted in the US army and has applied for parole on her behalf.
