In Orange County, Calif., dozens of immigrant parents have signed legal documents authorizing friends and relatives to pick up their children from school and access their bank accounts to pay their bills in the event they are arrested by immigration agents.

In Philadelphia, immigrants are carrying around wallet-size “Know Your Rights” guides in Spanish and English that explain what to do if they’re rounded up.

Around the country, President Donald Trump’s efforts to crack down on the estimated 11 million immigrants living illegally in the U.S. have spread fear and anxiety and led many people to brace for arrest and to change up their daily routines in hopes of not getting caught.

In El Paso, Texas, Carmen Ramos and her friends have developed a network to keep each other updated via text messages on where immigration checkpoints have been set up.

She said she also is making certain everything she does is in order at all times. She checks her taillights before leaving the house to make sure they are working. She won’t speed and keeps a close eye on her surroundings.

The unease among immigrants has been building for months but intensified in recent weeks with ever-clearer signs that the Trump administration would jettison the Obama-era policy of focusing mostly on deporting those who had committed serious crimes.

The administration announced Tuesday that any immigrant in the country illegally who is charged with or convicted of any offense, or even suspected of a crime, will now be an enforcement priority. That could include people arrested for shoplifting or other minor offenses, or those who simply crossed the border illegally. Some husbands and wives fear spouses who lack legal papers could be taken away. And many worry that parents will be separated from their U.S.-born children.
