President Trump’s ban on refugees and travelers from six majority-Muslim nations went partially into effect Thursday evening. Under a Supreme Court ruling earlier this week lifting a stay against the ban, people from Iran, Libya, Syria, Somalia, Sudan and Yemen who don’t have close family or business relationships may be denied visas and kept out of the U.S. On Thursday, the Trump administration said it will interpret “close family” to mean parents, children, siblings and in-laws. Among those excluded will be grandparents, grandchildren, uncles, aunts and cousins. The State Department said late Thursday it will allow fiancés from the affected countries to travel, after initially saying they, too, would be banned.
