Shriram Krishnan, an engineer with two master's degrees who has lived in the United States since 2003, was detained by ICE at McAllen International Airport on Wednesday while preparing to board a flight to Seattle to meet his newborn nephew. His wife, Dr. Ranjana Sarma, says Krishnan has no criminal history, and the family has paid taxes and had a pending green card application since 2014. Their 8-year-old son has not yet been told what happened and has been asking when his father will return. According to an immigration attorney quoted in the article, Krishnan may have been detained due to a legal technicality: while he holds a work permit, it does not necessarily grant legal status, and ICE is following a new protocol of detaining noncitizens who show work permits but lack legal status.
