Day Without Immigrants 2017 Day Without Immigrants (or A Day Without Immigrants) was a protest and boycott that took place on February 16, 2017, to demonstrate the importance of immigration, and to protest President Donald Trump's plans to build a border wall and to potentially deport millions of illegal immigrants. The strike called for immigrants not to go to work, to avoid spending money, and keep children home from school. People took part to show the importance of immigrants to the economy and also to protest possible racial profiling of U.S. citizens by immigration enforcement. The strike was planned on social media. People first started talking about the strike after the Women's March, and as the idea gained momentum, important people in the restaurant industry helped boost exposure.
