Due to the tens of thousands of migrants waiting in Mexico and the quick spread of knowledge about U.S. policy changes by traffickers, U.S. authorities have said that they anticipate an increase in the number of border crossings after Title 42 expires. After Title 42 is no longer in effect, U.S. Customs and Border Protection (CBP) has warned Congress to be ready for as many as 10,000 migrants a day crossing the southern border. This is roughly twice the daily average in March. Without a significant shift in policy, other official estimates imply daily migrant numbers might reach 11,000 to 13,000.
