Humanitarian Parole and Humanitarian Reinstatement are "humanitarian"-based forms of relief available to foreign nationals under very specific circumstances.
"Compelling emergencies" allow otherwise inadmissible foreign nationals to come into the United States for a temporary period of time to receive treatment or until the humanitarian situation is handled. The applicant must demonstrate that there are urgent humanitarian reasons or a significant public benefit; that he or she will come for a specific period of time during which the emergency or humanitarian situation will be taken care of. A request for re-parole must be approved by USCIS. A parole does not grant any immigration benefits.
A humanitarian reinstatement is available to the principal beneficiary of an approved Petition for Alien Relative (Form I-130). The petition must have been approved prior to the death of the petitioner. This does not apply to pending petitions. There are certain requirements that must be met such as having a substitute sponsor or filing an Intending Immigrant's Affidavit of Support exemption, when applicable.
