Why are some green-card holders and visa students being targeted for deportation under new US policies?

The US government’s recent immigration policies have led to the detention and deportation of green-card holders, visa students, and foreign nationals, sparking controversy. Cases like those of Fabian Schmidt, Ranjani Srinivasan, and others highlight how individuals with legal statuses or visas are being caught in enforcement actions, often due to past misdemeanors, misunderstandings, or political associations. The detention conditions and unclear enforcement grounds raise concerns about the fairness and transparency of current immigration practices.
