Immigrants in Brooklyn joined in a nationwide rally for changes to immigration laws Monday.

At exactly 12:16 p.m., immigrant workers, business owners and community members in Brooklyn and across the city will stopped what they were doing to protest. Some immigrants created a human chain along 5th Avenue. They want the public to know how much their work helps the economy.

Organizers of the rallies are called Monday the "National Day of Action" and "A Day Without Immigrants." All immigrants were called on to boycott work, school and shopping to show how much undocumented workers are needed in the communities.
