Trump has promised to deport all immigrants who are in the U.S. illegally, a plan that could affect an estimated 11.2 million people, according to the Pew Research Center, and cost up to $200 billion to implement, based on estimates from the American Action Forum.

Such a mass deportation effort would require a significant increase in federal resources. Currently, U.S. Immigration and Customs Enforcement (ICE) spends approximately $10,854 per deportation, according to government data.

To deport the entire estimated population of undocumented immigrants, this would require an expansion of detention facilities, transportation logistics, and manpower, potentially leading to the hiring of 85,000 new agents and the construction of thousands of additional detention beds.
