When a U.S. company wants to hire a foreign professional for temporary work, the process begins with one crucial step — filing Form I-129, Petition for a Nonimmigrant Worker.
This petition, submitted by the U.S. employer, establishes the legal basis for a foreign national to apply for a nonimmigrant employment visa such as H-1B, L-1, or O-1.
In this article, we explain what Form I-129 is, who must file it, which visa types it covers, and how USPassportApplicationOnline.com helps applicants and employers understand this important process.
What Is Form I-129?
Form I-129 is a petition filed by a U.S. employer or organization seeking to employ a foreign national temporarily under a nonimmigrant visa category.
It is submitted to the U.S. Citizenship and Immigration Services (USCIS), the government agency responsible for processing employment-based immigration petitions.
The form requests approval for a specific individual to work in the United States in a specialized occupation, executive role, cultural exchange, or other approved category.
Once USCIS approves the petition, it issues a Notice of Action (Form I-797) — confirmation that the petition has been granted.
The foreign worker can then use this approval notice to apply for the corresponding visa at a U.S. embassy or consulate abroad.
Without an approved I-129 petition, most foreign workers cannot proceed with their visa application process.
Which Visa Categories Use Form I-129?
Form I-129 applies to a wide range of nonimmigrant employment visas, including but not limited to:
-
H-1B – Specialty Occupations (for professionals with specialized knowledge or higher education).
-
L-1A/L-1B – Intra-company transfers (for executives, managers, or employees with specialized expertise).
-
O-1 – Individuals with extraordinary ability in science, arts, education, business, or athletics.
-
P-1/P-3 – Athletes, artists, and entertainers participating in specific events or programs.
-
Q-1 – Cultural exchange visitors.
-
R-1 – Religious workers.
-
H-2A/H-2B – Temporary agricultural and non-agricultural workers.
Each visa category has distinct eligibility requirements and documentation standards.
The I-129 petition must clearly demonstrate that the position and the foreign worker meet the criteria for the specific visa classification.
Employers are also responsible for providing supporting evidence, such as contracts, wage documentation, or proof of the employee’s qualifications.

Key Steps After Form I-129 Approval
Once the petition is approved by USCIS, the process continues at the international stage:
-
The applicant receives the Form I-797 Notice of Approval.
-
With this approval, they can submit Form DS-160 (Online Nonimmigrant Visa Application) via the U.S. State Department website.
-
The applicant schedules and attends a visa interview at a U.S. consulate or embassy in their country.
-
After the visa is issued, they can travel to the United States and begin employment under the conditions specified in the petition.
It’s important to note that approval of Form I-129 does not guarantee visa issuance — the consular officer still evaluates eligibility during the interview.
Proper preparation of both the petition and the subsequent visa application helps ensure a smoother process and reduces the risk of delays.
Conclusion
