Mexican President Andres Manuel Lopez Obrador cautioned residents of his country that the border isn’t yet “open” for unhindered migration into the United States during the Biden administration.

“Now, for example, that there is a U.S. immigration policy to regularize the situation of migrants, Mexicans, and our Central American brothers, people think that now, the doors are open, that President Biden is going to immediately regularize all migrants,” Lopez Obrador said on Thursday. “It is not true that everyone can go now to the United States and they will be regularized. That has not been defined yet. Our brother migrants should have this information so that they won’t be deceived by human traffickers, who paint a rosy picture.”
