MCALLEN - Mexican consulates across the country are letting fellow nationals in the U.S. know what to do if they’re detained by federal immigration authorities.

The government said people should find out what documents they must carry at all times and keep copies of that paperwork.

If they are unsure of what those documents are, they can contact the nearest consulate.

If authorities show up at their home, the consulate recommends them to ask for an arrest or search warrant. They should then make sure it was signed by a judge.

People can also ask to speak with the nearest consulate. The consulate discourages people from lying to authorities and using fake documents.

There are Mexican consulates in Brownsville and McAllen. One is located in 301 Mexican Boulevard Suite F2 and the other is located in 600 S Broadway St., respectively.
