WASHINGTON — President Donald Trump has backed an immigration overhaul that would reduce the number of permanent, legal migrants allowed in the US each year.
He joins Republican Senators Tom Cotton and David Perdue, who in February proposed a bill to cut legal immigration by 50 per cent over 10 years.
The Raise Act would end diversity lottery visas and curb the number of refugees offered permanent residency.
Immigration reform was a centrepiece of Mr Trump's presidential campaign.
But the bill has a long way to go before becoming law and would be likely to face resistance in Congress from members of both parties.
Republican Senator Lindsey Graham said that the bill would have a "devastating" impact on the economy in South Carolina - the state he represents.
