The senior Biden transition official, who spoke on the condition of anonymity, said those who have been waiting at the border, along with other vulnerable populations, will be a priority for processing and entry, rather than those who have recently arrived.

The official said migrants attempting to cross into the U.S. to claim asylum in the first few weeks of the new administration “need to understand they’re not going to be able to come into the United States immediately.”

The official also emphasized that any immigration legislation proposed by the Biden administration will be for undocumented immigrants already living in the U.S., not those who are considering arriving now.
