There’s a federal database of illegal immigrants like me. Erase it while there’s still time.

When I applied for the temporary status in 2013, I had to provide U.S. Citizenship and Immigration Services (USCIS) with every detail of my personal information — school records, bank accounts, my original Argentine passport and birth certificate and more, along with my address and every location I’d lived for the last 20 years. I included a check for $465 and went to a USCIS office near me in Miami to have my fingerprints and photograph taken. Since then, I have completed an application for renewal twice, with updates on my current address, everywhere I’ve lived since my previous application, and my current income. I received my most recent renewal just last month.

If Trump wants to use it to find undocumented immigrants, the Department of Homeland Security’s database of our addresses, fingerprints, employers and more could easily become a weapon instead of a shield. The database likely also includes information on thousands of Dreamers who applied and were denied for failing to pass a criminal background check or because they didn’t have sufficient evidence of continuous residence in the U.S. since June 2007, which is one of the guidelines for eligibility. When the program first launched, I volunteered at the law clinic that had helped me with my own application, and I remember many families struggling to produce the necessary documentation to prove their continuous residency. They have “outed” themselves to the federal government without benefitting from the program for the last four years.

Now Obama should order the database deleted before Trump is sworn in on Jan. 20.
