For purposes of this section only, an absence from the United States to conduct official business on behalf of the employing organization, or approved customary leave shall not be subtracted from the aggregated period of required residence or physical presence for the current or former G-4 officer or employee or the accompanying spouse and unmarried sons or daughters of such officer or employee, provided residence in the United States is maintained during such absences, and the duty station of the principle G-4 nonimmigrant continues to be in the United States. Absence from the United States by the G-4 spouse or unmarried son or daughter without the principle G-4 shall not be subtracted from the aggregate period of residence and physical presence if on customary leave as recognized by the international organization employer. Absence by the unmarried son or daughter while enrolled in a school outside the United States will not be counted toward the physical presence requirement.
Maintaining G-4 status for this purpose is defined as maintaining qualified employment with a "G" international organization or maintaining the qualifying family relationship with the G-4 international organization officer or employee. Maintaining status as an N nonimmigrant for this purpose requires the qualifying family relationship to remain in effect. Unauthorized employment will not remove an otherwise eligible alien from G-4 status for residence and physical presence requirements, provided the qualifying G-4 status is maintained.
