Which form is used by a U.S. citizen or LPR to establish a qualifying relationship for immigration purposes?

The correct form used by a U.S. citizen or Lawful Permanent Resident (LPR) to establish a qualifying relationship for immigration purposes is Form I-130. This form, known as the Petition for Alien Relative, is specifically designed to help U.S. citizens and LPRs sponsor their relatives for immigration to the United States. By filing Form I-130, the sponsor demonstrates their relationship to the family member who wishes to immigrate, which is a crucial step in the family-based immigration process.

This form verifies that the family relationship is legitimate and qualifies the relative for further immigration processing. Once approved, it allows the relative to apply for a visa or adjust their status, depending on their situation.

Other forms mentioned are utilized for different purposes. For instance, Form I-485 is used to apply for adjustment of status to a lawful permanent resident, Form I-864 serves as an affidavit of support to show that the immigrant will not become a public charge, and Form I-601 is used to apply for a waiver of inadmissibility. Each of these forms plays a distinct role in the immigration process, but none are specifically intended for establishing a qualifying familial relationship like Form I-130.
