<h1>Mass workplace immigration raid detains hundreds at construction site; issues on restraints, voluntary departure, removal authority</h1> Federal immigration authorities conducted a large workplace enforcement action at a battery factory under construction in Georgia, detaining hundreds of foreign workers who were held at an immigration detention center and subsequently transported to Atlanta for removal processing; more than 300 individuals departed the U.S. for their home country, while one national opted to remain. Diplomatic engagement between U.S. and foreign officials addressed use of restraints, classification as voluntary departure versus deportation, and temporary pauses in processing following instructions from the U.S. President. Legal issues include detention and removal authority, standards for use of restraints during transfers, diplomatic protections for foreign nationals, and potential visa-policy and investment consequences.
