President Donald Trump's attempt to limit birthright citizenship has been blocked by a federal judge. A preliminary injunction was granted against an executive order targeting "birth tourism". The injunction will remain in place until a class-action lawsuit is resolved.

The judge's ruling cited the Supreme Court, stating that children born on US soil are "citizens at birth". Birthright citizenship is currently guaranteed under law for those born on US soil, with some exceptions.

Further details on the ruling and lawsuit are available, including the judge's written statement and background on the 1868 law guaranteeing birthright citizenship.
