Final answer:
To apply for naturalization in the U.S., one must be a lawful permanent resident, not just a legal alien or resident. They must meet various criteria including residency, moral character, and language proficiency to be considered for citizenship.
Step-by-step explanation:
The statement "An applicant must be a U.S. citizen or legal alien/permanent residency" is not fully accurate in the context of applying for naturalization. To apply for naturalization in the United States, a noncitizen must meet several criteria, including being a lawful permanent resident (green card holder), residing in the U.S. for a specified period, demonstrating good moral character, and being able to speak, read, write, and understand English, among others. Permanent residents have certain legal rights and protections, such as the ability to live and work in the United States and receive some Social Security benefits.
