A court has denied a request to block new limits on work permits for migrants, allowing the tighter authorisation rules to remain in force while litigation continues, Bloomberg Law News reports.

The ruling matters for migrants who rely on employment authorisation documents to work lawfully while their immigration cases proceed. The challenged policy narrows who can obtain or renew those permits, and the court's refusal to halt it means the restrictions apply now rather than being suspended pending a final judgment.

A denial of interim relief does not end the case. The challengers can still pursue their claims on the merits, and a later decision could ultimately strike down or uphold the limits. Until such a ruling, the new restrictions govern work permit eligibility.

Migrants holding or seeking work authorisation under the affected categories should monitor announcements from US Citizenship and Immigration Services (USCIS) and the court's docket, as any subsequent order could change eligibility rules again.

Passport File will continue to track this litigation and any changes to work permit rules that follow from it.
