Donald Trump's new immigration decree will come into force on March 16 and will cut the  number of refugees in half  -- to around 50,000 -- compared to previous years.  The new decree will suspend the admission of refugees to the US for 120 days. It will not allow the citizens of six countries - Iran, Yemen, Libya, Syria, Somalia, Sudan, and Iraq – to enter the US for 90 days. At the same time, as the White House spokesman informed, the US visa and temporary residence permits already granted will not be canceled.
