Yes! You can use AI to fill out Form I-129, Petition for a Nonimmigrant Worker

Form I-129 has a Form Complexity Index of 70 out of 100, placing it in the complex complexity tier. This score is calculated deterministically from the form’s own structure using Instafill’s published Form Complexity Index methodology, so it can be reproduced and independently verified — it is not a subjective estimate.

For Form I-129 specifically, the score reflects 970 fillable fields across 38 pages, grouped into 38 sections. The number of fields is the largest factor in the base score (weighted 36%), followed by how difficult those fields are to complete based on their type, where free-text and signature fields count for more than simple checkboxes (26%). The number of pages that actually contain fields (15%), the amount of conditional “fill-only-if” logic (16%), and how many sections the form is divided into (7%) account for the rest of the base. On top of that base, the index adds points for tables and repeating lists, bundled instruction pages, and dense page layouts — capturing difficulty the base alone can miss.

In practical terms, a complex score means the form is demanding, with many fields, multiple pages and branching rules that are easy to get wrong. Instafill removes that effort entirely: our AI reads your information, maps each value to the correct field — including the conditional ones — and completes Form I-129 accurately in under a minute, with every field available for you to review before you download.

Form I-129, Petition for a Nonimmigrant Worker, is used by employers or prospective employers to petition the U.S. Citizenship and Immigration Services (USCIS) for a foreign national to come to the United States temporarily to perform services or labor, or to receive training, as a nonimmigrant worker. The form is also used to request an extension of stay or change of status for a nonimmigrant worker already in the United States.

Form I-129 can be used to request various nonimmigrant worker classifications, including but not limited to: H-1B (specialty occupations), H-1B1 (free trade agreement workers in specialty occupations from Chile and Singapore), H-2A (temporary agricultural workers), H-2B (temporary non-agricultural workers), H-3 (trainees or special education visitors), L-1A and L-1B (intracompany transferees), O-1 (individuals with extraordinary ability or achievement), P-1 (internationally recognized athletes or entertainers), P-2 (artists or entertainers under reciprocal exchange programs), P-3 (artists or entertainers in culturally unique programs), Q-1 (participants in international cultural exchange programs), and R-1 (religious workers).

The OMB No. (Office of Management and Budget Number) is a unique number assigned to the form by the Office of Management and Budget, which approves all federal forms that collect information from the public. The expiration date is the date until which the current version of the form is valid and can be used. This information is typically found in the top right corner of the form. However, without the current form in front of me, I cannot provide the specific OMB No. and expiration date for Form I-129. It is important to use the most recent version of the form, which can be found on the USCIS website.

In Part 1 of Form I-129, the petitioner is required to provide basic information about the petition, including the type of petition, the petitioner's name and contact information, the basis for the classification being sought, and whether an attorney or accredited representative is assisting with the petition. The petitioner must also indicate if they are filing for an individual worker or multiple workers under the same classification and provide information about the employer, such as the employer's legal business name, primary U.S. office address, and employer identification number (EIN).

The various supplements attached to Form I-129 serve to provide additional, classification-specific information required for the different types of nonimmigrant worker petitions. Each supplement is tailored to a particular visa classification and asks for details pertinent to that classification, such as the nature of the job or event, the beneficiary's qualifications, and other criteria that must be met for the specific nonimmigrant status being requested. The supplements ensure that USCIS receives all the necessary information to adjudicate the petition according to the requirements of the particular nonimmigrant classification.

The validity dates for the nonimmigrant worker's classification approval are specified in the approval notice (Form I-797) that USCIS issues to the petitioner upon approving Form I-129. These dates indicate the period during which the nonimmigrant worker is authorized to work in the United States under that specific classification. The petitioner should ensure that the employment start date and end date on Form I-129 align with the intended period of employment and comply with the limits of the specific nonimmigrant classification being requested.

A petitioner can indicate that they are a nonprofit organization on Form I-129 by providing the necessary information in Part 1 of the form, which asks for the type of petitioner. The petitioner should check the appropriate box that corresponds to their status as a nonprofit organization. Additionally, they may be required to submit supporting documentation to establish their nonprofit status, such as a determination letter from the IRS or other relevant evidence.

In Part 3 of Form I-129, the petitioner is required to provide detailed information about the nonimmigrant worker.

This includes the job title, duties, and requirements of the position, the start and end dates of employment, the full-time or part-time nature of the job, the location where the work will be performed, and the wage offered. The petitioner must also provide their Employer Identification Number (EIN), the number of employees in the company, the gross annual income, and the net annual income. This part of the form helps USCIS determine the eligibility of the employer and the validity of the job offer.

The petitioner must certify whether they will release or otherwise provide access to controlled technology or technical data to the foreign person in the United States. If such a release will occur, the petitioner must assert that they have a license from the U.S. Department of Commerce or U.S. Department of State, as required, or that such a release is not required by law. This certification is part of the compliance with the Export Administration Regulations (EAR) and the International Traffic in Arms Regulations (ITAR).

In Part 7 of Form I-129, the petitioner must provide a declaration affirming that all of the information provided in the form and any accompanying documentation is complete, true, and correct.

If the petitioner is an individual, they must sign themselves; if the petitioner is a company or organization, an authorized representative must sign. The signature must be original on paper forms, but for electronically filed petitions, an electronic signature may be used.

Part 9 of Form I-129 is the Additional Information section, which allows the petitioner to provide any extra details that were not included in the previous parts of the form due to space limitations or that require further explanation. This section can be used to clarify responses to earlier questions, to provide additional context, or to include information that the petitioner believes is relevant to the adjudication of the petition. The petitioner should reference the specific part and item number that the additional information relates to.
