Who traditionally serves as the petitioner on an I-130 petition?

The petitioner on an I-130 petition is a critical role in the immigration process, as this form is utilized to establish a relationship between a U.S. citizen or lawful permanent resident and a foreign national. The sponsor, who is typically a U.S. citizen or a lawful permanent resident, is responsible for submitting the I-130 petition to initiate the process for their family member to obtain a visa, allowing them to move to the United States.

This petition demonstrates the petitioner’s intention to support the immigrant financially and affirms the legitimacy of their familial relationship. Therefore, the process emphasizes the role of the sponsor as a vital participant, as they must provide evidence of their status and their relationship with the beneficiary. This is why the correct answer highlights the sponsor's role as the petitioner. The other options, while related to immigration processes, do not hold the responsibility of filing the petition.
