What is the process for dependents to apply for the O-3?

The O-3 is the visa category for dependents of an O-1 visa holder: the spouse and unmarried children within the age limit established for dependents. It allows the family to accompany the professional during their authorized stay in the United States, but does not, on its own, authorize the dependent to work.

The application typically follows the consular route and accompanies the principal’s process or comes shortly after. In general, the path involves:

• Gathering documents that prove the family relationship, such as a marriage certificate for the spouse and birth certificates for the children.
• Completing the nonimmigrant visa application form (DS-160), individually for each dependent.
• Paying the applicable fees and scheduling the appointment.
• Attending the interview at the U.S. consulate or embassy, when required, and presenting the original documents.

During the interview, the consular officer may request additional information to confirm the authenticity of the relationship and the intent to accompany the principal. Accuracy and consistency in the data help avoid delays.

Since rules can change and vary by consular post, it is worth checking the latest guidance on the official USCIS and Department of State websites or consulting a specialist before starting the application.
