"The court very clearly did not address the merits of birthright citizenship and they in fact stayed the executive order for another 30 days for everyone," New Jersey Attorney General Matt Platkin said.
Platkin adds that the president's approach to birthright citizenship is a recipe for chaos on the ground, and does harm to the states.
Local supporters of immigrants agree.
"I think to try to call the bluff of an administration that has been hell bent at ripping sections out of the U.S. Constitution... it is naive," said Amy Torres, the executive director of the New Jersey Alliance for Immigrant Justice.
New Jersey-based groups serving undocumented residents say the impact of the court's ruling is going to be felt far and wide.
"The fact that are kids will not be enrolling in school because there is a fear of, will my kid be picked up," said Hazel Applewhite, the CEO of Ironbound Community Cooperation.
New Jersey is among 22 states that sued over the president's use of an executive order to ban birthright citizenship.
"We're going to see more non-cooperation with things that we know are unholy and just wrong, that are hurting people," said Charlene Walker, executive director of Faith in New Jersey.
One woman Eyewitness News spoke to has an undocumented spouse and did not want to show her face because she is worried about his safety and sees Friday's ruling as an attack on people like her husband.
"We have to push back, and we have to stand up when something is wrong and say so, and stand up for people who are not able to do that for themselves," said a representative for American Families United.
