The United States has begun enforcing new visa restrictions targeting individuals accused of violating religious freedom in Nigeria, in a move aimed at curbing global religious persecution.

According to Mark Walker, the policy is already in effect and will be used to bar offenders from entering the country.

“We have already executed on this policy, and we will continue to subject perpetrators to additional scrutiny,” Walker said, confirming that enforcement has started.

He added that Washington will not tolerate individuals linked to persecution, stating, “If you engage in persecution, you are not welcome in America. The United States is safer when we keep those responsible for religious persecution from entering our homeland.”

The visa restriction framework was introduced in December by US Secretary of State Marco Rubio. It allows the US government to deny entry to anyone who “knowingly directs, authorises, funds, supports, or carries out violations of religious freedom.”

US lawmaker Chris Smith had earlier backed the measure, calling for sanctions and asset freezes on individuals and groups allegedly involved in religious rights abuses.

The proposal also referenced organisations such as the Miyetti Allah Cattle Breeders Association of Nigeria and Miyetti Allah Kautal Hore in relation to alleged violations.

Another US politician, Rabiu Kwankwaso, was previously mentioned in proposed sanctions discussions, though no official list of affected individuals has been released.

The US government says the policy is part of broader efforts to respond to religious violence globally and ensure accountability for those responsible.
