The number of illegal immigrants crossing into the US from Mexico went down by 40% from January to February, according to the US government.
Homeland Security chief John Kelly said the “change in trends” was a result of Donald Trump’s tough policies.
The president has signed an executive order for an “impassable physical barrier” on the US-Mexico border and issued new guidance on deportations.
The measures have been condemned by Mexico as “hostile” and “unacceptable”.
An estimated 11 million undocumented immigrants live in the US, many from Mexico.
Mr Kelly said on Wednesday that the number of “inadmissible persons” crossing the US-Mexico border had dropped this year from 31,578 to 18,762 in January to February – a period when the number of arrests of illegal immigrants normally increases.
