WASHINGTON (AP) — President-elect Joe Biden plans to unveil a sweeping immigration bill on Day One of his administration, hoping to provide an eight-year path to citizenship for an estimated 11 million people living in the U.S. without legal status.

The legislation puts Biden on track to deliver on a major campaign promise important to Latino voters and other immigrant communities. It provides one of the fastest pathways to citizenship for those living without legal status of any measure in recent years, but it fails to include the traditional trade-off of enhanced border security favored by many Republicans, making passage in a narrowly divided Congress in doubt.

Expected to run hundreds of pages, the bill is set to be introduced after Biden takes the oath of office Wednesday, according to a person familiar with the legislation and granted anonymity to discuss it.

Under the legislation, those living in the U.S. as of Jan. 1, 2021, without legal status would have a five-year path to temporary legal status, or a green card, if they pass background checks, pay taxes and fulfill other basic requirements. From there, it’s a three-year path to naturalization, if they decide to pursue citizenship.

For some immigrants, the process would be quicker. So-called Dreamers, the young people who arrived in the U.S. illegally as children, as well as agricultural workers and people under temporary protective status could qualify more immediately for green cards if they are working, are in school or meet other requirements.

The bill is not as comprehensive as the last major immigration overhaul proposed when Biden was vice president during the Obama administration.
