Form I-129, Petition for a Nonimmigrant Worker, is a U.S. Citizenship and Immigration Services (USCIS) form used by U.S. employers and qualifying petitioners to request authorization to employ a foreign national in the United States on a temporary, nonimmigrant basis under an eligible visa classification.
Form I-129 is an employer-filed petition. It does not grant a visa or permanent residence, but it is a required step for many employment-based nonimmigrant categories.
This guide explains who must file Form I-129, when it is required, which visa classifications it covers, required supporting evidence, filing fees, processing times, and what happens after approval.
Question
Details
What Is Form I-129?
Form I-129 is a USCIS petition used by U.S. employers and qualifying petitioners to request authorization to employ a foreign national temporarily in the United States under an eligible nonimmigrant visa classification.
Who Files Form I-129?
A U.S. employer, U.S. agent, or other qualifying petitioner files Form I-129. The foreign national worker is the beneficiary and cannot file the petition themselves.
When Is Form I-129 Required?
When an employer is hiring a foreign worker, extending a worker’s authorized stay, requesting a change of immigration status, or reporting material changes to approved employment terms.
Which Visa Classifications Use Form I-129?
Common classifications include H-1B, H-2A, H-2B, L-1, O-1/O-2, P, Q-1, R-1, and TN (when filed by an employer), among others.
What Fees Apply?
Filing fees can change and vary by classification and petitioner type and may include a base filing fee, Fraud Prevention Fee, ACWIA fee, Asylum Program Fee, and an optional Premium Processing fee.
Is Form I-129 a Visa?
No. Form I-129 is not a visa and does not grant permanent residence or authorize entry to the United States.
How Long Does Processing Take?
Processing times vary by classification, USCIS service center, and workload. For eligible Form I-129 classifications, Premium Processing provides USCIS action within 15 calendar days, but it does not guarantee approval.
What causes RFEs and denials?
RFEs or denials commonly result from missing evidence, filing errors, or failure to meet classification requirements.
What Happens After Approval?
Approval authorizes employment. Workers abroad may need a visa, while workers in the U.S. receive a new Form I-94 governing their stay.
What Is Form I-129?
Form I-129 is filed by a U.S. employer, U.S. agent, or other qualifying petitioner, not by the foreign worker themselves, to request authorization for:
A new nonimmigrant worker
An extension of stay for an existing worker
A change of status for a worker already in the U.S.
An amendment to an existing petition (such as job changes or employer restructuring)
If you are specifically applying for an H-1B specialty occupation visa, see our complete H-1B Visa guide and H-1B Visa Overview for eligibility, the cap and lottery process, and current fees.
Approval of Form I-129 allows the beneficiary to work only for the petitioning employer and only under the specific terms approved.
Important Legal Note
Form I-129 approval is not a visa and does not grant permanent residence.
Form I-129 Filing Fees
Filing fees vary depending on the visa category, the type of petition filed, and the size of the employer. Potential fees may include:
Base filing fee
Fraud Prevention and Detection Fee (required for certain visa classifications)
ACWIA training fee (required for certain visa classifications)
Asylum Program Fee
Premium Processing fee (optional)
USCIS offers reduced filing fees for certain small employers and qualifying nonprofit or governmental organizations, including reduced or exempt Asylum Program Fees, depending on petitioner type and classification.
The Asylum Program Fee helps fund USCIS’s asylum adjudication operations and is generally required for many employer-filed Form I-129 petitions, even when the petition itself is unrelated to asylum benefits.
Eligibility for reduced fees is based on USCIS criteria, such as whether the petitioner qualifies as a small employer, generally determined by the number of full-time equivalent employees, and varies by visa category and fee type.

Processing Time for Form I-129 and Premium Processing
Processing times for Form I-129 vary depending on the visa classification, the USCIS service center handling the case, and the overall volume of petitions being processed. Standard processing can take several months, and timelines may fluctuate throughout the year.
For certain visa classifications, USCIS offers Premium Processing, which allows petitioners to request expedited review for an additional fee. When available, Premium Processing guarantees that USCIS will take a qualifying action within 15 calendar days. A qualifying action may include an approval, denial, or a request for additional evidence, depending on USCIS’s review.

Important: Premium Processing guarantees faster USCIS action on the petition, but it does not guarantee approval. Availability may change based on USCIS policy and workload.
1. Confirm the Correct Visa Classification Before You Start
Many issues stem from selecting the wrong classification or supplement. Always confirm eligibility requirements for the specific visa category before preparing the petition.
2. Use the Current Accepted Form Edition
USCIS will reject petitions filed using an outdated or unaccepted form edition. Always download Form I-129 directly from the USCIS website and verify the edition date before filing.
3. Include All Required Supplements
Many classifications require additional I-129 supplements. Missing a required supplement is a common reason for rejection or delay.
4. Follow the USCIS Fee Schedule Carefully
Filing fees vary by classification and petitioner type. Pay close attention to whether separate payments are required and whether additional fees—such as the Asylum Program Fee—apply.
5. Verify the Correct Filing Address
USCIS filing addresses vary by classification, petitioner location, and whether premium processing is requested. Always confirm the correct address immediately before mailing.
6. Provide Clear and Organized Supporting Evidence
Supporting documents should clearly establish eligibility for the classification. Label exhibits and organize evidence so USCIS officers can easily follow the petition.
7. Document Maintenance of Status When Required
For extensions of stay or changes of status, include evidence that the beneficiary has maintained lawful status, such as Forms I-94, prior approval notices, and payroll or tax records.
8. Include a Well-Prepared Support Letter
A strong support letter explains the petition type, confirms eligibility, describes the job role, and clearly references supporting exhibits. This helps reduce confusion and Requests for Evidence (RFEs).
9. Do Not Assume Work Authorization Begins Upon Filing
In most cases, the worker may not begin employment until USCIS approves the petition. Exceptions are limited and classification-specific.
10. Double-Check Everything Before Filing
Before submission, review the petition for signatures, correct dates, consistent information, proper fees, and complete documentation. Small errors can lead to rejection, delays, or RFEs.
Using Form I-129 to Apply for a Change of Status to E-2 Status
When a foreign national is already present in the United States in a lawful nonimmigrant status (for example, on an F-1, B-1/B-2, H-1B, or other valid visa), it may be possible to change status to E-2 Treaty Investor status without leaving the U.S. This is done by filing Form I-129, Petition for a Nonimmigrant Worker, with U.S. Citizenship and Immigration Services (USCIS) and requesting a Change of Status to the E-2 classification.
What Form I-129 Does for an E-2 Change of Status
Form I-129 is the primary USCIS petition used by employers or qualifying parties to request a non-immigrant visa classification on behalf of a foreign national. While most commonly associated with employment-based classifications, USCIS also permits the use of Form I-129 to request a Change of Status to certain treaty-based classifications, including E-2 Treaty Investor status, provided the beneficiary is physically present in the United States in lawful status at the time of filing.
When filing Form I-129 for an E-2 Change of Status:
The petitioner (often the U.S. business entity owned or controlled by the investor) must complete Form I-129 and include the appropriate E-2 classification request.
Detailed supporting documentation should be submitted, demonstrating that the applicant meets the E-2 requirements — such as proof of nationality of an E-2 treaty country, investment in a bona fide enterprise, ownership/control over the enterprise, and sufficient funding.
What Happens When the I-192 E02 Visa Change of Status is Approved?
If approved, USCIS will issue an approval notice and update the beneficiary's I-94 record to reflect the new E-2 nonimmigrant status without the applicant needing to depart and re-enter the United States.
Eligibility & Practical Considerations
Not all foreign nationals in the U.S. can change status to E-2. To be eligible:
The applicant must be a citizen of a country that has a qualifying treaty with the United States for E-2 investor visas.
The applicant must currently be in lawful nonimmigrant status with a valid I-94.
Individuals present in the U.S. under the Visa Waiver Program (ESTA) generally cannot file for a Change of Status and must instead pursue consular processing abroad.
Advantages of Using Form I-129 for E-2 Change of Status
Filing Form I-129 for a Change of Status to E-2 can offer important benefits:
Remain in the U.S. throughout the adjudication process without needing to exit and re-enter the country.
Begin managing the E-2-qualifying business immediately upon approval of the status change.
Optionally, applicants can request premium processing to expedite USCIS adjudication where available.
However, it is important to note that a Change of Status approval grants E-2 status within the United States but does not provide an E-2 visa stamp for travel abroad. If the applicant travels outside the U.S. after a Change of Status approval, they will need to apply at a U.S. consulate for an E-2 visa stamp to re-enter the United States in E-2 classification.

Frequently Asked Questions
The following frequently asked questions address common issues employers, petitioners, and agents encounter when preparing and filing Form I-129, Petition for a Nonimmigrant Worker, including eligibility, filing requirements, fees, processing times, and related procedures.
What Is Form I-129 Used For?
Form I-129 is the USCIS form employers use to sponsor foreign workers for temporary employment in the United States. It allows an employer to request approval for a worker to be employed under a specific nonimmigrant visa category, such as H-1B, L-1, or O-1.
Who files Form I-129?
In most cases, Form I-129 is filed by a U.S. employer. In certain limited circumstances, a U.S. agent or supporting organization may file the petition on behalf of the employer or beneficiary, depending on the visa classification. The foreign national worker is typically the beneficiary, not the petitioner, for the classifications processed using Form I-129.
When Do Employers Need to File Form I-129?
Form I-129 is required when an employer is:
Hiring a foreign worker for the first time
Requesting an extension of a worker authorized stay
Requesting a change of the worker immigration status
Reporting material changes to the worker employment terms that require USCIS approval
Which Visa Classifications Use Form I-129?
Form I-129 is used for many employment-based nonimmigrant visa categories, including but not limited to:
Each classification may require additional supplements and supporting documentation.
Is Form I-129 a Visa?
No. Form I-129 is a petition filed with U.S. Citizenship and Immigration Services (USCIS), not a visa. If a visa is required, it is typically obtained after USCIS approves the petition, through the U.S. Department of State at a U.S. embassy or consulate. Once admitted to the United States, the worker Form I-94 governs the authorized period of stay and status.
Can a Worker File Form I-129 for Themselves?
No. A worker cannot file Form I-129 on their own behalf. Form I-129 must be filed by a U.S. employer, U.S. agent, or other qualifying petitioner, depending on the visa classification. The foreign national worker is listed as the beneficiary, not the petitioner.
Any suggestion that a worker can independently apply for an I-129–based work visa without a sponsoring petitioner is incorrect.
Can Form I-129 Be Filed Online?
In some cases, yes. USCIS allows online filing for certain Form I-129 classifications, depending on the visa category and current system availability. When online filing is available, USCIS system guides petitioners through the submission and payment process.
Not all Form I-129 petitions can be filed online, and many classifications still require paper filing by mail. Petitioners should always confirm filing options on the USCIS website before submitting.
Where Do I Mail Form I-129?
USCIS uses direct filing addresses for Form I-129 that vary by visa classification and, in some cases, by the state where the petitioner is located. USCIS publishes a resource titled "Direct Filing Addresses for Form I-129", and most petitions are submitted to USCIS lockbox facilities.
Because filing addresses can change, petitioners should always confirm and use the current USCIS address designated for their specific classification before mailing the petition.
What Is the "Edition Date" and Why Does It Matter?
USCIS requires petitioners to file the currently accepted edition of each form. The Form I-129 webpage lists the valid edition date, which appears at the bottom of the form. USCIS may reject or return a filing submitted using an unaccepted or outdated edition of the form.
What Supporting Evidence Is Required?
Required supporting evidence depends on the visa classification and whether the petition is requesting an initial classification, an extension of stay, a change of status, or an amendment due to changed employment.
For extensions of stay and changes of status, USCIS requires evidence that the beneficiary has maintained lawful status in the United States throughout their stay.
What Documents Are Commonly Used to Show Maintenance of Status in the U.S.?
USCIS provides examples of documents that may be used to demonstrate maintenance of status, depending on the beneficiary circumstances. Common examples include:
Copies of the beneficiary most recent pay stubs (if employed)
Form W-2 or IRS tax return transcripts for recent years (if applicable)
A copy of the beneficiary Form I-94
Copies of the beneficiary passport, travel document, or prior approval notices
These examples are not exhaustive. USCIS may require additional or different evidence based on the visa classification and the beneficiary specific immigration history.
If the Worker Is Already in the U.S., Do I Need Form I-94?
Yes. When filing Form I-129 for a foreign national already in the United States, USCIS requires a copy of the beneficiary Form I-94, which shows the worker current immigration status and authorized period of stay.
USCIS instructions also indicate that petitioners should submit a supporting letter explaining the reason for the extension or change, along with any additional evidence demonstrating continued eligibility.
How Are Filing Types (New, Amendment, Extension) Defined?
New Employment: Filed for a worker who is currently outside the U.S. or in the U.S. under a different classification than the one previously approved.
Amendment: Filed when there is an existing approved petition, but the job duties, work location, employer structure, or other material terms of employment have changed in a way that requires USCIS notification and approval.
Extension: Filed to continue the same employment under the same classification beyond the current expiration date, generally with updated evidence showing continued eligibility.
Can the Worker Start Working as Soon as We File?
It depends on the visa classification and the worker current immigration status. In many cases, the worker may not begin employment until USCIS approves the petition. Some classifications and situations allow limited continued or new employment authorization, such as certain extension or portability scenarios, but these exceptions are narrowly defined and category specific.
What Happens If a Petition Is Missing Evidence or Has Errors?
If a Form I-129 filing contains basic errors, such as an incorrect filing fee, use of an unaccepted form edition, or missing required signature, USCIS may reject the petition and return it without processing.
If USCIS accepts the filing but determines that required evidence is missing, incomplete, or unclear, it may issue a Request for Evidence (RFE) or other notice requesting additional documentation. USCIS fee guidance also cautions that submitting incorrect fees can result in rejection.
How Long Does Form I-129 Take to Process?
Processing times for Form I-129 vary widely depending on the visa classification, the USCIS service center handling the petition, current workload, and whether USCIS issues a request for additional evidence. The most reliable way to estimate processing time is to use the USCIS Processing Times tool and select the appropriate form, classification, and service center.
What Is Premium Processing and How Do I Request It?
Premium Processing is an optional expedited service offered by USCIS for certain eligible petitions and requests, including specific Form I-129 classifications. When Premium Processing is available, USCIS guarantees that it will take action on the petition, such as approval, denial, or a request for evidence, within the designated processing timeframe.
To request Premium Processing, petitioners must file Form I-907, Request for Premium Processing Service, and pay the required fee. Form I-907 may be filed concurrently with Form I-129 or submitted after the petition has been filed, if permitted for the specific classification.
Does Premium Processing Guarantee Approval?
No. Premium Processing does not guarantee approval. It guarantees that USCIS will take a qualifying action on an eligible petition within the premium processing timeframe. That action may be an approval, denial, or a request for additional evidence, depending on USCIS review.
If Multiple Fees Apply, Can They Be Paid Together?
It depends on the visa classification and the specific fees required. In some cases, USCIS allows multiple fees to be combined into a single payment. In other situations, the USCIS fee schedule and Form I-129 instructions require separate payments for certain add-on fees.
Because improper payment can result in rejection, petitioners must carefully follow the category-specific payment instructions in the USCIS fee schedule and the Form I-129 instructions to ensure fees are submitted correctly.
Do I Need to Pay an Asylum Program Fee?
Often, yes. The Asylum Program Fee applies to many employment-based filings, including multiple Form I-129 classifications, but whether it is required depends on the petitioner type and the specific classification.
What Are the Most Common Reasons Form I-129 Filings Are Rejected or Delayed?
Form I-129 petitions are often rejected or delayed due to filing errors such as using an outdated form edition, submitting the wrong filing fees, mailing the petition to an incorrect address, missing required supplements, or failing to include evidence of maintenance of status for extensions or changes of status.
What Should Be Included in an Extension of Stay Support Letter?
For an extension of stay, USCIS instructions indicate that petitioners should include a support letter explaining the reason for the extension, along with a copy of the beneficiary Form I-94 and any additional evidence required for the specific classification.
A well-prepared support letter typically:
Restates the beneficiary job role and duties
Confirms the beneficiary continued eligibility for the classification
Explains why the extension is needed
Clearly references and organizes the supporting exhibits submitted with the petition
Can We File One Petition for Multiple Workers?
It depends on the visa classification. Some Form I-129 categories allow multiple beneficiaries on a single petition, while others require separate filings for each worker. Rules and limits vary by classification.

The entire process of getting an EB-5 visa is handled in a professional way by Mark Davies and his team. EB-5 is a wonderful option for anyone considering moving to the United States if you have the means. I was hoping to use the H-1B route for my children, but it became unreliable and so I looked to the EB-5 visa instead. It is great for anyone who has the resources. Mark gives you the first meetings himself which gives you great comfort. Both Mark and Sanjay are abundantly available and I even had the pleasure of hosting them at my house.

I'm in the process of extending my L-1 visa. I submitted a few questions regarding my case, and he contacted me back almost immediately, both by email and telephone. Unlike other attorneys I met before, he gave me the impression of knowing off the top of his head what kind of visa I have, and what actions had to be taken to extend it. He is very thorough and clear regarding the process and what to expect in terms of timelines and issues that may arise. He is constantly in contact, so you definitely know he's working on your case.
