O-3 Law and Legal Definition
Spouses and children under the age of 21 (dependents) of O-1’s or O-2’s are eligible for the O-3 visa. It allows them to reside with the principal applicant. O-3 status allows an individual to attend school but may not work in the U.S.
A petition, Form I-129, needs to be submitted with the form for the O-1 holder. Once USCIS approval is obtained the applicant will have to continue the rest of the application at the consulate. The US consulate will require the I-129 petition receipt number and an interview and digital fingerprint scan is required for all visa applicants.
The O-3 visa is valid for the duration thought to necessary for the principal applicant, O-1 holder, to accomplish the task, but is not to exceed 3 years.
O – 3 visa holders are not exempt from entry into the US-VISIT program and will also need to register their entry into the US and their departure.
