A panel of the 9th US Circuit Court of Appeals found that the Trump administration can terminate Temporary Protected Status for 300,000 immigrants from Sudan, Nicaragua, Haiti and El Salvador. This could also mean the end of TPS for countries such as Honduras.
USCIS has stated they are reviewing the decision and will announce an update shortly. The result of this decision could lead to hundreds of thousands of current TPS holders being put in removal (deportation) proceedings after decades in the United States with lawful status.
However, the decision was made by a panel of the 9th Circuit Court, and the plaintiffs will ask the full court to review the decision, so there is hope that this decision will be reviewed and overturned.
