International organization aliens (G-1 to G-4) are admitted without time limitation and are permitted to remain as long as the Secretary of State continues to recognize them as members of this class. There is no requirement that they must have a foreign residence to which they intend to return. G-5 attendants, servants and personal employee group are usually admitted initially for a period not exceeding three years. G-5 aliens may apply for extensions of temporary stay in two-year increments by attaching a written statement from the principal alien describing the current status and intended employment of the applicant.
Dependents of G-1 and G-3 aliens may apply for permission to work if there is a reciprocal work arrangement between the United States and the principal alien's state of nationality. A G-4 dependent of an officer or employee of an international organization may obtain approval to accept employment whether or not there is a reciprocal work agreement in force between the United States and the principal alien's state of nationality.
