United States President Donald Trump is set to sign several executive orders, including one on building a border wall with Mexico, this week to crack down on immigrants -- one of his central campaign promises -- and could suspend immigration from some Muslim nations, media reports have said.
Officials said the addition shows the measure was set on the basis of security and was not a 'Muslim ban'.
Since 1975, the United States has welcomed more than 3 million refugees from all over the world.
