Deferred Action Childhood Arrival recipients are set to gather in Battery Park Saturday to begin a 230-mile walk to Washington, D.C.

The fate of 800,000 immigrants rests in the hands of eight Supreme Court justices. The Obama-era policy allows those brought to the U.S. illegally as children to legally work and avoid deportation.

The highest court in the country is set to begin hearing oral arguments on DACA next month to decide whether to allow the program to continue. Many worry it will end.

In response, about 200 people are signed up to walk to D.C. in solidarity with the policy and those affected.

Lidsy Contreras is one of those immigrants -- a Pace University graduate. She can't participate in the march because she has to work, but agrees that they have no other option but to stand up for themselves.

"If this decision were made to end DACA, I don't know what my future would look like," says Contreras. "This is all I've known, this country is what I call home, I pledge allegiance to this flag every day."

Lower courts have previously blocked President Donald Trump from rescinding DACA. The Supreme Court will likely have their decision next year.
