The US Supreme Court has agreed to decide the legality of President Donald Trump’s latest travel ban, which targets people from six Muslim-majority countries.
The court is due to hear arguments in April and will rule by the end of June.
But it has already allowed the policy to go into effect while legal challenges continuem BBC News reports.
The third version of Mr Trump’s directive affects travelers from Chad, Iran, Libya, Somalia, Syria and Yemen.
It also bans travelers from North Korea and certain government officials from Venezuela from entering the US.
Opponents say it is unconstitutional and discriminatory and that in making it Mr Trump has exceeded his legal authority.
But supporters say the president is fulfilling his campaign promises to protect Americans and defend national security.
