Two days after an illegal Mexican immigrant living in the United States was arrested and marked for deportation, Mexico has warned its citizens to "take precautions."

"The case involving Mrs. Garcia de Rayos illustrates a new reality for the Mexican community living in the United States, facing the most severe implementation of immigration control measures," Mexico's Foreign Ministry said, reports CNN.

The statement added that Mexican embassies worldwide "have intensified their work of protecting fellow nationals, foreseeing more severe immigration measures to be implemented by the authorities of this country, and possible violations to constitutional precepts during such operations and problems with due process.

"It is important that fellow nationals familiarize themselves with the different scenarios they might encounter and know where they can go to receive new information and know all their rights."

Guadalupe García de Rayos was arrested Wednesday while performing a required check-in with Immigrations and Customs Enforcement officials. She has met with ICE every year since she was arrested for and convicted of using a fake social security number in 2008.

García de Rayos, who is a Mexican citizen, had not been deported during former President Barack Obama's two terms in office because she was deemed a low threat. Under President Donald Trump's new rules, however, officials have begun the process of sending her back to Mexico.

García de Rayos has two children in the U.S.

Protesters took to the streets in Phoenix Wednesday night after it became public that the 36-year-old would be deported.
