The US and Mexico have agreed to a plan that allows some Venezuelan migrants to enter the US - but those who arrive illegally will be sent back to Mexico.
It is hoped the deal will ease pressure at the US-Mexico border, where a steady flow of Venezuelans continues to arrive as they flee the crisis-hit nation.
Starting immediately, flights will be arranged for 24,000 migrants to arrive in the United States.
More than six million people have left Venezuela in the past five years.
The exodus is one of the largest migrations in the world, fuelled by violence, food, fuel and medicine shortages, and repression by the government of President Nicolás Maduro.
