Certain family members can petition for close relatives and can sponsor those relatives for a green card to stay in the United States permanently. Some possibilities are listed below:
Family Petitions - U.S. citizens or permanent residents can petition for their family members to either come to the U.S. or obtain legal status if they are already in the U.S.
Inadmissibility Waivers - Applicants who are barred from applying for a green card due to unlawful entry, past criminal activity, or any reason, may be eligible for a waiver of those inadmissibility grounds.
Citizenship - Permanent residents are eligible to naturalize after they have held lawful permanent resident status in the U.S for a certain amount of time.
