WASHINGTON (Reuters) - U.S. green card holders from Syria and six other Muslim-majority countries travelling outside the United States need to check with a U.S. consulate to see whether they can return, senior U.S. administration officials said on Saturday.

New restrictions on immigrants and refugees in an executive order signed by President Donald Trump will mean legal permanent residents who have passports from the seven countries have to be cleared back into the United States on a case-by-case basis, an official told reporters in a briefing.
