A temporary block has been placed on a new immigration rule. This rule would have altered the duration of stay for certain international students and exchange visitors in the US. The change was initially set to occur on Tuesday.

Advocacy groups had filed a lawsuit, citing potential negative impacts on international students and the economy. A judge in Boston made the decision to block the rule. Further details about the blocked rule and its potential effects are available.

The Department of Homeland Security has not commented on the decision or whether they will appeal.
