One of the most common ways to obtain the commonly known as a green card or U.S. Permanent Residency is through a family petition. The family member may be a Legal Permanent Resident (“LPR”) or a U.S. citizen (“USC”). The length of time with respect to the approval of the petition depends whether the petitioner is LPR or USC. There are two groups of family-based immigrant visa categories, one is the immediate relatives and the other includes family preference categories.
