There is nothing remarkable about the recent decline in foreign born population in comparison with the immediate past under Biden, when 945k left in April 2024 and 896k left in June 2023.
The numbers are noisy if nothing else, and go back only to January 2007.
That said, the January surge is probably more about the revisions of the data for the previous year than about anything else.
About 6.1 million foreign born entered the country in 2021 through 2024 in this data, after about 629k left in 2020. In 2025 through May, about 849k have left, but May is notably flat from April.
You could just as easily say the May numbers indicate Trump's policies have been a complete failure.
I would be more sanguine about attributing an exodus of foreign born to the new Trump policies if the leavers were much larger in number than recently, but they are not.
In my book, Trump needs to get the foreign born population back down to 43.5 million, his 2019 peak. Anything less is not a victory.
