What is the function of the I-604 form?

The I-604 form serves the specific purpose of making a determination regarding a child for adoption. This form is utilized by the U.S. Citizenship and Immigration Services (USCIS) to evaluate the eligibility of a child who is being considered for adoption by a U.S. citizen or permanent resident. The process typically involves assessing whether the child qualifies as an eligible orphan and if the adoption meets legal requirements.

In contrast, the other options represent functions associated with different forms within the immigration process. For instance, the form tied to registration for classification as a refugee pertains to seeking asylum or refugee status, which is not the purpose of the I-604. The application for naturalization is a separate process for individuals looking to become U.S. citizens and does not involve children or adoption directly. Lastly, the refugee/asylee relative petition relates to the sponsorship of family members by those who have been granted refugee or asylum status, which is distinct from the adoption context addressed by the I-604. Thus, the focus of the I-604 on adoption determination makes it the correct answer.
