The Trump administration has said it will re-examine green cards issued to individuals who immigrated to the US from 19 countries, BBC reported.

The head of the US Citizenship and Immigration Services, Joseph Edlow, said the president had directed him to conduct "a full scale, rigorous re-examination of every green card for every alien from every country of concern".

When asked by the BBC which countries were on the list, the agency pointed to a June proclamation by the White House that included Afghanistan, Cuba, Haiti, Iran, Somalia and Venezuela, according to BBC.
