Donald Trump’s attempt to leapfrog over lower courts in order to put a stop to recent rulings that have allowed some Deferred Action for Childhood Arrivals (DACA) renewals to resume was denied by the Supreme Court this week, but it doesn’t lessen the urgency to pass permanent, legislative protections as soon as possible.

Even as renewals continue, without congressional action the rate of DACA recipients losing protections daily will increase dramatically after March 5. ”I go to sleep uncertain, and I wake up with the fear of losing my family,” said Osvaldo Rodriguez. He’s one of a dozen young immigrants and allies walking from New York City to Washington, D.C. to call on Congress to act:

Equipped with water, a change of socks and a smartphone, Rodriguez and 16 other people walked through the Garden State live-streaming their journey. He and his cohorts delivered updates and shared their stories Saturday along the 17-mile walk. There’s Ricardo Cruz Ramirez, 32, who was brought to the country as a toddler from Mexico. He lacked legal status until his 20s when he was detained by Immigration and Customs Enforcement, and he fought his case in the courts. Nearly a decade later, Ramirez is a naturalized U.S. citizen. But his family members are not. “I have a brother. He’s a DACA recipient. For this walk that we’re doing we are sending the message of a clean Dream Act, which protects the youth but not criminalize my parents,” he said. “I have a mother who is undocumented.”

Fernanda Madrigal, another DACA recipient and mom of a 5-year-old child, flew from California to participate in the walk. Madrigal said she had plans to take the LSAT and apply for law school, but Trump’s ending DACA last September threw her life—and future—into uncertainty. “I hope that people understand that this is our home,” she said. “We are fighting to stay home. This is where our families are.”
