Parole is a form of discretionary relief and temporary in nature for the most part. When a non-citizen seeking admission to the United States is not clearly qualified for admission, the immigration officer may choose to release the non-citizen on parole pending further investigation. Immigration authorities may also grant parole for humanitarian reasons or reasons of public interest. While on parole, the person can travel within the United States. However, they are not officially "admitted" and are treated under the law in substantially the same way as someone who is arriving at the border. They are normally not entitled to the same greater procedural rights in a later removal proceeding of a person who has been admitted and inspected.
