Mr. Na, a graduate of Hunter College, was a beneficiary of the 2012 program Deferred Action for Childhood Arrivals, which protected certain undocumented children who were brought to the United States by their parents; it remained unaffected by the Supreme Court’s decision this week. Mr. Jeong was also covered by the deferred action program, enabling him to graduate from City College of New York and land an engineering job that starts next week.

They came to the rally to show solidarity.

“It’s not just Latino struggles, it’s everybody’s struggles,” said Jung Rae Jang, 26, a community organizing fellow at MinKwon who came from South Korea at 15. One of the designated speakers at the rally, he urged his fellow immigrants to keep fighting for reform and to encourage others to vote.

Mr. Jang said that he would like to organize more events in collaboration with the Hispanic community, but “language barriers are a problem,” he said.

But he also said that Asians did not seem to have been as affected by deportations as the Hispanic community, adding, “so it’s hard to relate in that aspect.”

Ester Rim, an intern at MinKwon, could, however, relate to the disappointment in the Supreme Court. Born in Brazil to Korean parents, she moved with her family to Queens when she was 4. Her parents, she said, would have been eligible to apply for administrative relief because her sister had become a permanent resident.

Ms. Rim, attending Macaulay Honors College at the City University of New York on a scholarship, did not even tell her parents about the possibility that they could have qualified. “I can’t even imagine how much heartbreak they would’ve gone through,” she said.
