U.S. lifts travel ban on Chad citizens -White House

WASHINGTON, April 10 (Reuters) - President Donald Trump lifted a U.S. travel ban on citizens from Chad on Tuesday after a six-month U.S. government review found improvements in the African country's security standards, the White House said.

The Trump administration added Chad to a revamped travel ban list in September after it said the Chadian government had failed to send proof it had taken adequate security measures to prevent terrorists from traveling to the United States.

With Chad taken off the list, seven countries - Iran, Libya, Syria, Yemen, Somalia, North Korea and Venezuela - are still subject to the travel restrictions.

Trump's critics have said his travel ban unfairly singled out Muslims, and violated U.S. law and the Constitution.

Courts struck down the first two versions of Trump's travel ban, and the current one is narrower in scope than its predecessors. The U.S. Supreme Court will consider its legality this spring, and a decision is expected in June.
