This bill, known as the 9/11 Immigrant Worker Freedom Act , establishes a pathway for certain individuals who provided critical services following the September 11, 2001, terrorist attacks to adjust their status to lawful permanent residents. Applicants must apply within 18 months of the Act's enactment, with potential extensions for compelling circumstances. Eligibility extends to aliens who worked or volunteered in rescue, recovery, debris cleanup, or related support services at specific sites, including lower Manhattan, the Staten Island Landfill, the Pentagon, or Shanksville, Pennsylvania, within defined periods. The legislation specifies eligibility criteria based on the location and duration of service, such as at least 4 hours in lower Manhattan between September 11-14, 2001, or 80 hours by July 31, 2002. It also covers vehicle-maintenance workers exposed to debris and members of fire or police departments or cleanup contractors at the Pentagon or Shanksville sites. Individuals applying for this adjustment of status will receive work authorization during the pendency of their application. Furthermore, the bill includes provisions for fee waivers for applicants who receive means-tested benefits, have an income no greater than 250 percent of federal poverty guidelines, or face extraordinary financial hardship, ensuring that applying for a fee waiver does not negatively impact public charge determinations. To protect applicants, the bill mandates confidentiality of information provided in applications, prohibiting its use for immigration enforcement purposes or referrals to U.S. Immigration and Customs Enforcement, with limited exceptions for assisting application consideration, identifying fraud, national security, or investigating felony offenses. Importantly, granting lawful permanent resident status under this Act will not reduce the number of immigrant visas otherwise available under the Immigration and Nationality Act. The Secretary of Homeland Security is directed to publish interim final rules within 90 days to implement the Act, allowing immediate applications.
