H-1B Amendment

Your H-1B employee moves from your Austin office to your Denver office, and the transfer goes through HR without an immigration review. Six months later, USCIS asks why the worksite on file does not match your payroll records.

Worksite changes are the most common trigger for an H-1B amendment, and the cost of fixing one quickly has climbed: premium processing on Form I-129 rose to $2,965 on March 1, 2026.

The filing itself is straightforward once you know what counts as a material change. Timing is the part that needs a process behind it. This guide covers when a filing is required, what it costs, how long it takes, and what to do if you are already behind.

What is an H-1B amendment?

An H-1B amendment is an updated Form I-129 petition that your company files with USCIS (U.S. Citizenship and Immigration Services) when the terms of an approved H-1B job change in a significant way. You are not starting over. The original approval stays in place, and the amended petition tells the agency what is different.

Because the H-1B classification is tied to a specific role, wage, and worksite, USCIS treats the approved petition as a description of the job it authorized. When the real job drifts from that description, the petition stops matching the employment. No lottery, cap, or new registration is involved.

When is an H-1B amendment required?

You need to file whenever a material change affects the terms and conditions of employment described in your approved petition. The governing regulation, 8 C.F.R. § 214.2(h)(2)(i)(E), requires an amended or new petition to reflect those changes, and it has to be filed before the change takes effect.

Four situations account for most worksite changes and job changes that require a filing:

• A move outside the current MSA: If your employee will work outside the metropolitan statistical area (MSA) covered by the certified labor condition application (LCA), you must obtain a new LCA, and that alone makes the move material.
• A material change in job duties: Shifting an employee into substantively different work, or into a role with different educational requirements, changes the job USCIS approved. Incremental growth within the same specialty occupation does not.
• A change in ownership or corporate structure: Mergers, acquisitions, and spin-offs can require a new filing. A successor-in-interest that assumes the predecessor's immigration liabilities can often avoid one, so run the successor-in-interest analysis before the deal closes.
• A reduction in hours or wage: Moving someone from full-time to part-time, or cutting pay below the wage listed on the LCA, breaks the terms of the certified application.

Why MSA boundaries matter more than employers realize

If you operate in more than one city, this is where your exposure sits. An H-1B amendment for location change does not turn on whether your employee stayed with the same company or in the same state. It turns on whether the new worksite location falls inside the MSA listed on the certified LCA.

To check, find the county of the new worksite and compare it against the MSA definition behind the original LCA. The Department of Labor's area of intended employment covers the MSA plus locations within normal commuting distance, so a move across a metro line can be short in miles and still trigger a filing.

A new area also brings a new prevailing wage determination, often higher than what you pay today.

Remote work is the version that catches teams off guard. H-1B amendment remote work rules follow the employee's home address: if someone relocates and works from a residence in a different area of intended employment, that residence becomes a worksite and has to appear on an LCA.

Reddy Neumann Brown attorneys reported in February 2026 that USCIS has been comparing LCA locations against payroll records and employee addresses to find exactly these discrepancies.

Changes that do not require a filing

Not every change triggers a petition, and unnecessary filings cost you money and invite scrutiny. Three exceptions in USCIS guidance following the Simeio decision cover most of them:

• Moves within the same area of intended employment: You do not file a new petition, but you still have to post the original LCA notice at the new worksite for 10 business days.
• Short-term placement: Under 20 C.F.R. § 655.735, you can place a worker at a site outside the LCA area for up to 30 workdays in a one-year period, extendable to 60 if the employee keeps a workstation at the permanent worksite and lives in that area. Short-term placement also requires you to cover lodging, travel, and per diem costs.
• Non-worksite locations: Conferences, seminars, and peripatetic travel that keeps the employee at any one location only briefly are not worksites.

Promotions sit in a fourth category. You only file an H-1B amendment for promotion or title change when the duties themselves change materially. A raise or a new job title within the same specialty occupation generally does not, though a significant increase may still require a new LCA at the higher wage level.

Material vs non-material change: how USCIS decides

The line between the two determines whether you file, and USCIS draws it around eligibility rather than inconvenience. The H-1B amendment material change standard asks a single question: would the change have affected the original adjudication or the underlying LCA?

That framework comes from Matter of Simeio Solutions, LLC, 26 I&N Dec. 542 (Administrative Appeals Office, or AAO, 2015), which held that moving an H-1B worker to a geographic area requiring a new certified LCA is a material change. More than a decade later, it remains the reference point every immigration attorney works from.

The 2025 modernization rule reinforced it by directing adjudicators to defer to prior approvals involving the same parties and the same underlying facts. That cuts both ways: consistency is rewarded, and an unexplained departure from what was approved before stands out.

How to file an H-1B amendment

Once you have confirmed a filing is required, sequence matters more than paperwork. Each step has to be finished before your employee's circumstances change:

1. Obtain a new certified LCA. The H-1B amendment new LCA requirement is the step most often missed. File with the Department of Labor for the new worksite or wage, post the required notice, and wait for certification.
2. Gather employer documentation. You will need the certified LCA, a support letter describing the role and any changed job duties, corporate documents behind an ownership change, and client letters if the employee sits at a client site.
3. Gather employee documentation. Your employee provides a passport and visa page, the most recent I-94 arrival record showing their authorized period of stay, prior H-1B approval notices, and recent pay statements.
4. File the amended H-1B petition. Submit the current edition of Form I-129 with the H Classification Supplement, the certified LCA, and supporting evidence. Mark it as an amended petition so USCIS does not treat it as a new filing.
5. Decide on premium processing. H-1B amendment premium processing costs $2,965 and obligates USCIS to act within 15 business days. That action can be an approval, a denial, or a request for evidence (RFE).
6. Confirm work authorization before the change. Your employee can begin working under the new terms as soon as USCIS receives the amended H-1B petition. Keep the receipt notice as proof of the filing date.

Important note: If the petition is denied but the original approval is still valid, your employee has to return to the worksite and terms it covers. An H-1B amendment denied after someone has relocated is easier to manage when the fallback is already decided, so agree on one before the move.

Late filings and worksite discrepancies

If you have already found a gap, filing late is still better than leaving it open. A late petition does not cure the period your employee spent working outside the approved MSA, but it puts an accurate record in front of USCIS and closes the gap going forward.

Expect questions. USCIS may issue an RFE asking for the timeline and scope of work at the unapproved site, and in more serious cases it issues notices of intent to revoke alleging that the employer failed to adhere to the approved petition and certified LCA.

A finding that your employee did not maintain H-1B status can follow them into a future extension of stay, a visa interview, or a green card filing.

Cost and timeline for an H-1B amendment in 2026

An amendment is one of the less expensive H-1B filings, because two of the biggest fees do not apply. Your total depends on your company's size and whether you need a fast decision:

USCIS confirms on its H and L filing fees page that an amended H-1B petition without an extension request is exempt from the ACWIA fee, putting a typical standalone filing at $1,380 for a larger employer, or $760 for a small one.

H-1B amendment processing time under standard adjudication generally runs a few months and varies noticeably between service centers, so check the USCIS processing times tool before promising a date. Lighthouse prepares these filings in under 3 weeks.

These costs sit with the employer. Passing the H-1B amendment fee to your employee, directly or through a deduction, risks dropping their actual wage below the required wage on the LCA.

H-1B amendment vs transfer vs extension

You use Form I-129 for all three, which is why they get confused. What separates them is the trigger and the filer:

You can combine filings. You can request an H-1B extension in the same petition as an amendment, which is common when a worksite change lands near the end of the validity period and saves a second base fee. That does reintroduce the ACWIA fee if it is your company's first extension for that employee.

What changed in 2025 and 2026

Two developments shape how your filings are handled today. The Department of Homeland Security's H-1B modernization rule, effective January 17, 2025, codified the requirement to amend before a worksite move takes place and wrote the exceptions for same-area moves into the regulations.

The same rule tightened the specialty occupation definition and expanded USCIS site visit authority.

The second is the $100,000 payment created by a September 2025 presidential proclamation. It never applied to timely filed amendments, extensions, or change of status petitions for people already in the United States.

A Massachusetts district court vacated it on June 8, 2026, and on July 24, 2026 the First Circuit declined to reinstate it during the appeal. The Department of Homeland Security has said it will comply while the case continues, and that it plans to collect if the order is lifted.

The practical takeaway is unchanged: a denied petition that sends your employee abroad for a new H-1B visa is a costlier outcome than it was two years ago.

Building a worksite tracking process

Late filings usually begin as routine HR decisions that never reach immigration counsel. Your best protection is a rule that treats location and role changes as immigration events rather than administrative ones, built on three habits:

• Require advance notice: Ask managers and HR to notify counsel before any office transfer, long-term remote arrangement, client site change, or substantial change to job descriptions.
• Audit twice a year: Compare active LCAs and approved petitions against payroll addresses, withholding locations, and current job duties.
• Verify boundaries, not distances: Confirm the MSA for each worksite location rather than assuming proximity is enough.

The takeaway

Your amendment obligations are easier to meet than to fix. Build the reporting habit that surfaces material changes while there is still time to file in advance, and the rest is a predictable filing with a predictable cost.

Frequently asked questions on H-1B amendments

What does an H-1B amendment mean?

It means you have filed an updated petition telling USCIS that the job it approved has materially changed. Your employee's H-1B status continues, and they keep working under the new terms once the agency receives the filing.

What are the new amendments to the H-1B visa?

The two biggest recent changes to the H-1B visa are the modernization rule that took effect in January 2025 and the wage-weighted cap selection rule effective February 27, 2026, which gives higher-wage registrations more entries in the lottery.

What is Trump's new H-1B rule?

The September 2025 proclamation imposing a $100,000 payment on certain new petitions for beneficiaries abroad. A federal court vacated it in June 2026, and it remains unenforceable after the First Circuit declined to restore it on July 24, 2026. If you are amending or extending status inside the United States, it never applied.

When should we file an H-1B amendment?

Before the change takes effect. Once you hold the certified LCA and have filed the petition, your employee can start at the new location or under the new job title without waiting for the approval notice.

Can our employee work while an H-1B amendment is pending?

Yes. They can begin working under the amended terms as soon as USCIS receives the petition, and their employment authorization continues while it is pending. Keep the receipt notice on file, and be ready to return them to the prior worksite if the petition is denied.

What happens if we file the amendment late?

You file as soon as you find the gap. The late petition does not cure the period your employee worked outside the approved MSA, so expect an RFE about the timeline and scope of that work, and document what you did to correct it.

Does our employee need a new visa stamp after an amendment?

Not while they remain in the United States. The visa stamp is the foil a U.S. consulate places in a passport to request entry, and it is separate from H-1B status, which the I-94 record and approved petition govern. An expired stamp only matters for re-entry after international travel.

What are the fees for a visa stamp if our employee needs one?

The application fee for a petition-based nonimmigrant visa is $205 per person, including dependents. Reciprocity fees may apply based on nationality, and a $250 visa integrity fee has been enacted but is not yet on the State Department's schedule. Check the current fee page before budgeting.
