The bill tries to change the city's charter by including a new chapter with provisions for enabling green card holders and those with work authorization to register to vote and participate in citywide elections by producing a separate municipal voter registration. Adams backed the concept when he was campaigning for mayor earlier this year.
"We cannot be a beacon to the world and continue to attract the global talent, energy and entrepreneurship that has allowed our city to thrive for centuries if we do not give immigrants a vote in how this city is run and what our priorities are for the future," Adams announced in February, according to the New York Daily News.

"Nothing in this chapter shall be construed so as to confer upon municipal voters the right to vote for any state or federal office or on any state or federal ballot question," the bill states.

"We have the votes, it's going to be a very big deal," said Council Speaker Corey Johnson, who has scheduled the vote despite misgivings from Mayor de Blasio.

"I do have reservations, but obviously I want to see exactly what they're doing," de Blasio told reporters.
