Mexico has opened legal aid centres at consulates in 50 US cities, in a move designed to protect its citizens from tougher immigration enforcement, BBC reports.
Mexico is worried about the impact that guidelines issued last month by President Donald Trump will have on the lives of its citizens.
Mr Trump ordered federal agents to join local police and immigration officers to enforce deportation procedures.
The new defence centres will provide free legal assistance for Mexican citizens who feel that their rights in the US are being threatened.
There are an estimated 11 million illegal immigrants in the US. Six million of them are reportedly Mexican citizens.
