Nationality is an important issue in governments and their national s international relationships. Nationality is a political and spiritual relationship in attaching a person to a government. There are two criteria in granting nationality: Jus sanguinis (based on blood or descent) and Jus soli (based on birth place). In Jus sanguinis (based on blood or descent) these factors should be clarified: discriminatory or non-discriminatory application of Jus sanguinis, Lineage in jus sanguinis, Conditional and absolute application of jus sanguinis.
