The Trump administration is considering making it harder for foreigners living in the United States to get permanent residency if they have received certain public benefits such as food assistance, in a move that could sharply restrict legal immigration.

The Department of Homeland Security has drafted proposed new rules seen by Reuters that would allow immigration officers to scrutinize a potential immigrant's use of certain taxpayer-funded public benefits to determine if they could become a public burden.

For example, U.S. officials could look at whether the applicant has enrolled a child in government preschool programs or received subsidies for utility bills or health insurance premiums.
