When starting a process for the O visa, it is important to understand that the petition for classification as a nonimmigrant worker is made through Form I-129, which is the central petition document. However, depending on the case, there are additional forms and documents that accompany the I-129 to ensure all USCIS (United States Citizenship and Immigration Services) requirements are met.

One of the extra forms that may be part of the petition is the G-28, if the petitioner chooses to be represented by an immigration attorney. This document, the Notice of Entry of Appearance as Attorney or Accredited Representative, allows the attorney to follow the process with USCIS.

Additionally, for dependents of the primary beneficiary (such as spouses and children), it is common to prepare Form I-539 for requests to extend or change status, which occurs separately but alongside the main petition.

In the specific case of the O visa, the I-129 instructions also guide the inclusion of a supplement for the classification of an individual with extraordinary ability, detailing evidence and specific information related to the beneficiary”s field of expertise. This supplementary documentation aims to demonstrate that the applicant truly possesses extraordinary abilities recognized in their area of work, meeting the established criteria.

It is essential to strictly follow United States immigration laws and check all official USCIS guidelines when preparing your O visa petition. Consulting reliable sources and, if necessary, seeking support from specialized professionals can help avoid mistakes, scams, and guarantees of results that do not align with the reality of immigration processes.

Always verify the required documentation and complementary forms according to the specific case, ensuring all information is up to date in accordance with current regulations. Remember: each process has its particularities and it is vital that all documentation, including additional forms, is prepared carefully to meet all legal requirements.
