For a century, immigration registry has provided a legal means for undocumented immigrants to secure a lawful status on the basis of their long-standing residence in the United States. However, Congress has not updated the law since 1986, and the eligibility dates prevent most undocumented immigrants in the U.S. today from applying. By advancing the date, Congress could allow millions of undocumented immigrants who have lived in the U.S. for a long time to once again access a legal, existing path to legal status and citizenship.
