Donald Trump has promised to carry out a large-scale deportation operation, potentially involving millions of people living in the US without legal permission.

The operation would involve federal, state, and local law enforcement and could cost more than $967 billion over 10 years, according to the American Immigration Council.

Undocumented immigrants contribute significantly to tax revenue, paying $8,889 per person in federal, state, and local taxes in 2022, according to the Institute on Taxation and Economic Policy.

Trump's plans could impact various sectors, potentially eliminating 22% of American farmworkers, 15% of construction workers, 8% of service workers, 8% of manufacturing workers, and 6% of transportation workers.

Immigrant rights groups are preparing legal challenges against Trump's proposed deportation plans, which include rescinding programs like Deferred Action for Childhood Arrivals.
