Who may be charged to the same country as the principal in an immigrant visa petition?

The correct answer identifies a spouse accompanying the principal as someone who may be charged to the same country in an immigrant visa petition. In immigration law, a principal applicant can include certain family members as derivatives in their visa application, allowing them to immigrate under the same petition. A spouse of the principal applicant falls under this category of derivative beneficiaries.

When an immigrant visa petition is filed, not only does it establish eligibility for the principal, but it can also extend eligibility to immediate family members, which typically includes spouses and children. This unity in processing helps streamline the journey for families who seek to immigrate together.

The other choices do not share the same direct eligibility under typical derivative visa provisions. For instance, while a parent accompanying a child may be there in a support capacity, they are not automatically charged to the same country as a derivative. Similarly, siblings and adult children have different visa processing pathways and are not included as immediate relatives of the principal in the context of most immigrant petitions. Hence, those categories do not typically allow for charging to the same country in immigration petitions, unlike the spouse, who is inherently linked to the principal in this context.
