A nurse who fled Cuba as part of the Caribbean nation’s largest exodus in more than six decades needed a place to stay in Mexico as she waited to legally enter the U.S. using a government app. A woman who had lived her whole life in the same Tijuana neighborhood was desperate for medical help after a dog attack left her with wounds to her legs. A mutual acquaintance brought the two women together. Nurse Karla Figueredo stayed with Martha Rosales for three days in October 2023, waiting for a border appointment booked through the CBP One app and treating Rosales’ dog bites. When Figueredo left for the U.S., she got Rosales’ permission to give her name to other migrants. Word quickly spread and Rosales made her home part of a roster of at least three dozen migrant shelters in her hometown on the U.S.-Mexico border, temporarily housing people who use the CBP One app. “I told God that if they didn’t amputate my feet, I would help every Cuban,” said Rosales, 45, who was using a wheelchair after being attacked by five dogs until Figueredo helped heal her wounds. CBP One has brought nearly 1 million people to the U.S. on two-year permits with eligibility to work but could go away once President-elect Donald Trump takes office. Figueredo, 25, now works as a medical assistant in the Houston area and keeps in touch with Rosales, who quit her job as a bank cleaner to focus on her migrant shelter. The people Rosales houses, mostly Cubans, refer to her as “’Tía Martha” (Aunt Martha) as she cooks pancake breakfasts, throws birthday parties and shuttles them to their CBP One appointments. Supporters say CBP One has helped bring order to the border and reduced illegal crossings. But Trump has said he would end it as part of a broader immigration crackdown. Critics say it prioritizes a lottery system over people who have long lived in the U.S. illegally while paying taxes and people who have waited years for visas. Dayron Garcia, a doctor in Cuba who heard about Rosales from a nephew, applied with his wife and children and plans to settle with a friend in Houston. He said Rosales’ house “feels like family” and that “CBP One has been a salvation.” “It’s a guarantee,” Garcia, 40, said. “You enter with papers, with parole.” CBP One began under Trump and changed under Biden U.S. Customs and Border Protection debuted CBP One near the end of Trump’s first term as a way for customs brokers to schedule inspections and for visitors with short-term visas to extend stays. The Biden administration extended its use to migrants to replace an opaque patchwork of exemptions to a pandemic-related asylum ban that was then in place. CBP One is popular with Cubans, Venezuelans, Haitians and Mexicans, likely because advocates in their communities promote it. Illegal border crossings by Cubans plunged under CBP One from a peak of nearly 35,000 in April 2022 to just 97 in September. Demand for appointments has far outstripped supply, with an average of about 280,000 people competing for 1,450 daily slots toward the end of last year, according to CBP.
