WASHINGTON — In a city where expense account meals are a central part of power players’ lives, some of Washington’s best-known restaurants will close their doors on Thursday in solidarity with a national campaign to draw attention to the power and plight of immigrants.

The campaign, spread on social media and messaging apps, has called for a “day without immigrants.” It asks foreign-born people nationwide, regardless of legal status, not to go to work or go shopping in a demonstration of the importance of their labor and consumer spending to the United States’ economy.

Activists and groups in cities across the country have picked up the call, reposting fliers found online, and in some cases organizing demonstrations to coincide with the event. Several activists said that they did not know how the campaign began or how many people would heed it, and that as far as they knew, there was no national organization behind it.

But the dining scene in Washington, where the new Trump administration is taking a hard line on immigration and deportation, took notice. At least a few dozen restaurants in and around the Beltway have committed to staying closed on Thursday. Others have said they would offer limited service in the expectation that many of their employees would be out for the day. Some restaurants in other cities, including several of the Blue Ribbon restaurants in New York, have joined in.
