May have to do with the definition of “refugee”. When Trump was President, he was pretty much only allowing provable refugees to cross over into the US for a time. Biden is letting in most everybody. No need to claim refugee status. So, it is very possible fewer are claiming refugee status under Biden . . . there is no reason to make the claim anymore.

Probably counting only those who are actually coming through the main gate legit. The fence still has plenty of “holes” in it.
