With an executive order signed on Friday, President Trump began implementing the ‘extreme vetting’ of Muslims he promised during his campaign. All refugees are now barred from entering the US for 120 days. Syrian refugees face an indefinite ban. For 90 days, all entry has been suspended for citizens of seven Muslim majority countries: Syria, Iraq, Iran, Sudan, Libya, Somalia and Yemen. Yesterday, it was confirmed that the ban on entry includes people with green cards who happened to be out of the US when the order was signed. They cannot return home.
