What section grants USCIS officers the authority to administer oaths regarding a person's privilege to reside in the United States?

The correct choice is based on the authority granted to USCIS officers under the Immigration and Nationality Act (INA). Specifically, INA § 287(b) empowers designated officers, including those at USCIS, to administer oaths in relation to immigration applications, including those for asylum. This provision ensures that if an individual is applying for a privilege such as residency or asylum, the officer can legally administer oaths necessary for these processes.

The other options refer to different aspects of immigration law and processes. INA § 101(a)(42) defines "refugee," which is relevant to asylum claims, but it does not provide the authority to administer oaths. G-28 is a form that serves as a notice of entry of appearance as an attorney or accredited representative but is not related to oath administration. Similarly, G-28I refers to a notice of appearance for accredited representatives of organizations, lacking any authority related to administering oaths. Thus, A is the only answer that specifically addresses the authority for administering oaths, which is essential in the context of verifying the eligibility of applicants for certain privileges under immigration law.
