This bill, titled the "America First Citizenship and Allegiance Act," aims to significantly strengthen naturalization requirements, reaffirming American citizenship as a solemn act of allegiance and membership in the political community. It seeks to ensure applicants demonstrate good moral character, fidelity to the Constitution, and a favorable disposition towards the United States, moving beyond mere administrative status. The legislation's core purposes include enhancing civics and English requirements, preventing ineligible individuals from naturalizing, and imposing strict consequences for fraud. The bill amends the Immigration and Nationality Act to require a sufficient understanding of English for reading, writing, speaking, and understanding the oath of allegiance. It also mandates substantial knowledge of U.S. history, constitutional structure, and civic obligations, with the examination covering specific topics like the Declaration of Independence, Constitution, Bill of Rights, and duties of citizenship. The exam must be in English, require an 80% passing score, and dedicate at least 50% of questions to core constitutional documents. Furthermore, the legislation defines actions that disqualify an applicant from demonstrating attachment to constitutional principles or a favorable disposition to the U.S. These include knowingly engaging in or supporting terrorism, advocating for government overthrow, participating in political violence, assisting criminal organizations, or acting as a foreign agent. Concealing such affiliations or making false statements about allegiance also serves as a basis for denial, though protected speech or lawful association are explicitly safeguarded. A new provision mandates that applicants receive instruction on the meaning of the oath of allegiance in English, covering allegiance to the U.S., renunciation of foreign ties, and the duty to defend the Constitution. Applicants must then certify in writing, under penalty of perjury, that they understand the oath and are willing to take it without mental reservation, ensuring full comprehension of this solemn commitment. The bill establishes severe consequences for fraud and concealment in the naturalization process, mandating denial for knowingly making false statements, concealing material facts, or using fraudulent documents. A permanent bar from naturalization is imposed for serious fraud involving terrorism, espionage, foreign agency, violent crimes, human trafficking, unlawful voting, or false claims of U.S. citizenship. Other material fraud or concealment results in a 10-year bar , and such conduct is not cured by withdrawal or correction after detection. Credible evidence of fraud must be referred to relevant law enforcement agencies, and applicants denied naturalization due to fraud will be prioritized for removal if otherwise removable. The bill also significantly increases criminal penalties for naturalization fraud and false statements, with imprisonment terms ranging from 10 to 25 years for offenses linked to terrorism or foreign agency. An "America 250 Citizenship Initiative" is established to strengthen naturalization materials and civics education, emphasizing constitutional principles and civic duties. Finally, the legislation requires an annual report to Congress for five years, detailing naturalization applications, approvals, denials (with specific reasons), waivers granted, and referrals made for fraud. The Secretary must also promulgate regulations within 180 days to implement these new requirements, covering the examination, oath instruction, attachment determinations, and fraud consequences, thereby ensuring the integrity and rigor of the naturalization process.
