WASHINGTON, Jan 4 (Reuters) - The United States plans to accept up to 30,000 migrants per month from Cuba, Nicaragua, Haiti and Venezuela under a program paired with expulsions of people from those countries caught at the U.S.-Mexico border, U.S. and Mexican officials said. He said earlier in the day that he intended to visit the southwest border but that details were still being finalized. "I'm going to be making a speech tomorrow on border security, and you'll hear more about it tomorrow." Biden, who took office in January 2021, has struggled operationally and politically with record numbers of migrants caught crossing the U.S.-Mexico border, and migration is expected to be on the agenda at the meeting. Republicans have criticized what they say are lenient border security policies, while Biden officials say they are trying to create a more orderly and humane system.
