WASHINGTON  — The Trump administration’s decision to end special protections for nearly 200,0000 Salvadoran immigrants filled many Salvadoran families with anxiety dread Monday, raising the possibility that they will be forced to abandon their roots in the U.S. and return to a violent homeland they have not known for years, even decades.

Homeland Security Secretary Kirstjen Nielsen gave Salvadorans with temporary protected status until Sept. 9, 2019, to leave the United States or face deportation. El Salvador becomes the fourth country since President Donald Trump took office to lose protection under the program, which provides humanitarian relief for people whose countries are hit with natural disasters or other strife.

The decision, while not surprising, was a severe blow to Salvadorans in New York, Houston, San Francisco and other major cities that have welcomed them since at least the 1980s.

Guillermo Mendoza, who came to the United States in 2000 when he was 19 years old, was anguished about what to do with his wife and two children who are U.S. citizens.

“What do I do? Do I leave the country and leave them here? That is a tough decision,” said Mendoza, a safety manager at Shapiro & Duncan, a mechanical contractor company in Rockville, Maryland, near Washington.
