FREMONT, Neb. (AP) — A Nebraska city’s ordinance that bans renting homes to immigrants living in the country illegally is having little effect because Fremont officials haven’t been able to determine applicants’ citizenship status.

The federal government is refusing to provide information about an individual’s immigration status because Fremont doesn’t collect enough information.

So Fremont officials haven’t revoked any rental permits since the city of about 26,000 started enforcing the ordinance last year. Voters originally passed the ordinance in 2010, but its enforcement was delayed while lawsuits were resolved.

The rules require Fremont residents to pay $5 and swear they have legal permission to live in the United States. Landlords are prohibited from renting to anyone without a permit.
