Form I-129S: Blanket L Petition Filing, Fees, and Extensions

Form I-129S is the nonimmigrant petition a company with an approved Blanket L petition uses to transfer an individual employee to the United States as an L-1 intracompany transferee without filing a fresh Form I-129 for each person. The employer completes the form, and the employee presents it at a U.S. consulate, at a port of entry (if Canadian), or through USCIS if already in the country. A government officer then decides whether that specific transfer fits under the employer’s blanket approval. The tradeoff for skipping a separate USCIS petition is that the individual employee’s qualifications get closer scrutiny at the interview, so how you complete the form and what you bring with it matters.

Who Can Use Form I-129S

Two things have to be true before you file. The employer must already hold an approved Blanket L petition (Form I-129 with LZ classification), and the employee must fit one of the qualifying L-1 roles.

The employee has to be a manager, executive, or specialized knowledge professional. L-1A managers and executives primarily oversee professional staff or manage a key function of the organization. L-1B specialized knowledge workers hold advanced knowledge of the company’s products, services, or proprietary methods that isn’t readily available in the general labor market.

One rule catches employers off guard: under the blanket process, L-1B workers must also qualify as “professionals,” meaning they hold at least a bachelor’s degree or equivalent.¹ That degree requirement does not apply to L-1B workers transferred through individual (non-blanket) petitions.

Whatever the role, the employee must have worked full-time for the qualifying foreign entity continuously for at least one year within the three years immediately before seeking admission.² The foreign employer and U.S. petitioner must share a qualifying corporate relationship as parent, branch, subsidiary, or affiliate.

If the blanket petition itself expires or is revoked, employees already in L-1 status can remain until their own authorized period ends, but no new I-129S can be filed under that blanket.

Filling Out the Form

Form I-129S is free on the USCIS website and runs to ten parts.³ Before you start, pull the Petitioner’s Receipt Number from the approved Form I-797 Notice of Action for the blanket petition. That number is what ties the individual employee to the pre-approved blanket.

The parts cover:

Part 1: employer information, including the blanket petition receipt number.
Part 2: the proposed U.S. position, intended employment dates, and any prior U.S. stays.
Parts 3–5: the employee’s biographical data, proposed U.S. employment, and foreign employment history.
Part 6: certification about whether the employee will access controlled technology or technical data, tied to export control compliance.
Parts 7–9: signature blocks for the petitioner, any interpreter, and any preparer other than the petitioner.
Part 10: additional information space.

The job description gets the closest look. For L-1A roles, spell out what the employee will manage: which departments, functions, or teams, and make it plain that day-to-day operational tasks aren’t the core of the job. For L-1B roles, describe the specific proprietary knowledge the employee holds and why it’s needed at the U.S. site. Generic phrasing like “will oversee operations” invites follow-up questions or denial.

Supporting Evidence to Bring

The form alone won’t get the transfer approved. The employee should carry a documentation packet to the consular interview or port of entry:

A copy of the blanket petition approval notice (Form I-797), proving the employer’s blanket is active.
The completed Form I-129S. Three signed copies are standard for consular interviews.
Evidence of qualifying foreign employment: employment verification letters, pay records, or similar proof of full-time work for the foreign entity for at least one continuous year within the past three.
Evidence of the role’s nature: organizational charts, job descriptions, and staffing details showing the position is genuinely managerial, executive, or requires specialized knowledge.
For L-1B blanket cases only, evidence of a bachelor’s degree or its equivalent.¹

For L-1A cases, USCIS policy directs officers to evaluate managerial or executive capacity based on the “totality of the evidence” rather than headcount alone, considering the scope of the employee’s authority, the organization’s structure, and whether other staff handle operational and administrative work so the transferee can focus on management.⁴ A small office isn’t automatically disqualifying, but expect harder questions about what the person actually does each day.

Where to File

Where the form goes depends on where the employee is and their nationality.

At a U.S. Consulate

Employees outside the United States who need a visa present the completed Form I-129S at their scheduled visa interview at a U.S. Embassy or Consulate.⁵ The consular officer reviews the documents, questions the employee about prior experience and the intended U.S. role, and decides whether the transfer fits the blanket. If approved, the officer endorses the Form I-129S and issues an L-1 visa stamp. Two endorsed copies typically come back: one for the employee, one for the employer’s records.

At a Port of Entry (Canadian Citizens)

Canadian citizens are visa-exempt and can present Form I-129S directly to a U.S. Customs and Border Protection officer at a designated Class A port of entry on the U.S.-Canada land border or at a pre-clearance station in Canada.² No consular appointment, no visa stamp. The CBP officer endorses the form and issues an I-94 arrival record on the spot.

With USCIS (If the Employee Is Already in the U.S.)

If the employee is already in the United States and needs a change of status to L-1 or an extension of stay, the employer files Form I-129 (Petition for a Nonimmigrant Worker) together with the completed Form I-129S directly with USCIS.⁵ That is the only scenario where I-129S goes to USCIS rather than to a consular or CBP officer.

Fees

Costs stack from different sources depending on the employer and the filing path.

The employee applying at a consulate pays a $205 Machine Readable Visa (MRV) fee for the L category, typically by credit card or bank deposit before or during the interview.⁶ Some nationalities also owe a separate reciprocity fee that varies by country.

The employer pays a $500 Fraud Prevention and Detection Fee whenever the petition is for an initial grant of L-1 status, a change of status to L-1, or authorization for an L-1 worker to change employers, no matter where or with which agency it’s filed.⁷ The fraud fee does not apply to extensions of stay with the same employer.

A $4,500 Public Law 114-113 fee applies when the employer has 50 or more U.S. employees and more than half hold H-1B, L-1A, or L-1B status. It is required only for initial L-1 petitions or petitions to change employers, and applies to petitions filed before October 1, 2027. It cannot be waived and is nonrefundable regardless of outcome.⁸

When Form I-129 is filed with USCIS (extensions of stay or changes of status), an Asylum Program Fee of $600 applies to employers with more than 25 full-time equivalent employees; smaller employers pay a reduced amount.⁹ This fee applies only to USCIS filings, not to I-129S presentations at consulates or ports of entry.

Premium processing is available on USCIS filings by submitting Form I-907 with a $2,965 fee, which guarantees action within 15 business days.¹⁰¹¹ Premium processing is not available for I-129S filings at consulates or ports of entry, since those are adjudicated in person.

Between the MRV fee, fraud fee, and the possible PL 114-113 fee, total costs for a single initial blanket L transfer can run from about $705 to over $5,200 depending on the employer’s size and workforce composition, before attorney fees.

How Long the Endorsement and the Stay Last

Several clocks run at once, and mixing them up is one of the more common mistakes in blanket L cases.

For initial applicants, the endorsed Form I-129S is valid for the lesser of three years from the adjudication date or the end date the employer requested on the form. For renewals, the consular officer must also account for the employee’s remaining time under the statutory maximum.¹²

The individual maximum stay is seven years for L-1A managers and executives and five years for L-1B specialized knowledge professionals.¹³ Time previously spent in H or L status with any employer counts toward those caps. An employee who has maxed out generally must spend at least one year outside the United States before qualifying for a new period of L or H stay.

The practical consequence: an employee can hold a valid L visa stamp and still be denied entry if cumulative L and H time has hit the cap. Track prior periods carefully.

Separately, the blanket petition itself is initially approved for three years, after which the employer can request an indefinite extension. If USCIS denies that extension, the company must wait three years before filing another blanket petition and must use individual I-129 petitions in the meantime.¹³

Extending an Employee’s Stay

When an employee’s authorized period of admission is about to expire but ends before the blanket petition’s validity runs out, the employer has two choices: file an extension with USCIS, or have the employee depart and seek readmission abroad.

To extend without leaving, the employer files three things with USCIS:⁵

Form I-129, Petition for a Nonimmigrant Worker
A new Form I-129S
A copy of the employee’s previously approved Form I-129S

USCIS grants extensions in increments of up to two years, but the total stay cannot exceed the L-1A or L-1B statutory maximums above.

Family Members

The spouse and unmarried children under 21 of an L-1 employee qualify for L-2 status, but they are not included on the I-129S itself. They apply separately, either by requesting an L-2 visa at a consulate or by filing Form I-539 if already in the United States. L-2 stay matches the L-1 principal’s dates.¹⁴

Since November 2021, L-2 spouses are employment authorized incident to status, so the right to work comes automatically with L-2 admission and no separate EAD application is required.¹⁴ A spouse who wants a physical EAD card as proof of work authorization can still file Form I-765, but it’s optional. L-2 children may attend school but cannot work, and their L-2 status ends when they marry or turn 21, whichever comes first.

If the Form Is Denied at the Consulate

There is no formal appeal from a consular visa denial. Consular officers hold sole authority over visa adjudications, and their decisions are not reviewable by USCIS or any other agency.¹⁵ Not every denial is a dead end, though.

If the denial is under INA Section 221(g), meaning the consulate found the application incomplete or in need of additional documentation, the applicant has one year to submit the missing items to the same consulate without paying a new application fee. If administrative processing is involved, the consulate will make contact when it’s complete.¹⁵

For other denials, the applicant can reapply by submitting a new visa application and paying the fee again. Reapplying without changing anything rarely produces a different result. If the officer questioned whether the role truly qualifies as managerial or specialized knowledge, the employer should consider filing an individual I-129 petition directly with USCIS instead of relying on the blanket. An individual petition gets a full USCIS adjudication with a written decision, and a USCIS approval carries significant weight if the employee then returns to the consulate for visa issuance.
