Spouses and unmarried children under 21 of the treaty investor, regardless of nationality, may receive derivative E visas in order to accompany the principal alien. Dependents are not authorized to work in the United States. They can live and study in the U.S. without any additional permits, but must apply for work authorization to accept employment. The spouse of an E-2 holder may obtain employment authorization by filing form I-765, together with supporting documentation, with the appropriate immigration service center. They will be authorized to work for the period of admission and/or status of their spouses, but not to exceed two years. Spouse and children of principal E-2 visa holders can attend school without change of status.

The temporary departure from the United States of the principal trader or investor shall not affect the derivative status of the dependent spouse and minor unmarried children, provided the familial relationship continues to exist and the principal remains eligible for admission as an E nonimmigrant to perform the activity.
