H-1B Change of Status Is Approved. Now What? An Employer Compliance Checklist

After an H-1B change of status takes effect, employers must make sure the employee’s job, title, wage and worksite match the approved petition and LCA, start FICA withholding, close out the STEM OPT Form I-983 training plan, and avoid hasty amendments that could draw USCIS scrutiny.

If your new hire moved from F-1 OPT to H-1B on October 1, you probably felt relief when the approval notice arrived. That relief is fair. But at Orange Law, we tell employers the same thing every year: approval is the start of your compliance duties, not the end of them.

The first few weeks in H-1B status are when small mismatches get caught or get buried. This guide walks you through what to check, in what order, and where employers most often slip.

What does an H-1B change of status mean for employers?

A change of status means your employee, already in the U.S. on F-1 OPT, STEM OPT or another status, officially becomes an H-1B worker without leaving the country. From the validity start date on their Form I-797 and I-94, they work under the terms of your approved Form I-129 petition and certified Labor Condition Application (LCA).

Those two documents now define the job. Whatever they say about duties, wage and location is what the employee must actually be doing.

This also applies if your employee’s change of status takes effect later, for example when a cap-subject petition is still pending. In that case, run the same checks on the day H-1B status begins.

Step 1: Make sure the real job matches the petition

This is the most overlooked step. Your employee may have been in the same role for a year or more on OPT, and the role may have shifted since the petition was prepared months ago.

On the H-1B start date, confirm that:

• Duties match the petition and support letter
• Job title is the same across HR systems, offer letters and org charts
• Salary is at or above the wage on the LCA. If they earned less on OPT, the raise must start with the first H-1B pay period
• Worksite matches the LCA. For remote or hybrid staff, the home office counts as a worksite and must be covered, with the LCA notice posted and the public access file complete

Our team has a separate walkthrough on new H-1B employee employer actions if you want the wider picture, including benefits and I-9 requirements.

When does a change require an amendment?

If something doesn’t line up, fix it quickly, but fix it correctly.

• Moving the employee to a worksite outside the LCA’s area of intended employment generally needs a new LCA and an amended petition filed before the move.
• Moving within the same area usually needs a new LCA notice posting, but typically not an amendment.
• Material changes to duties, occupational classification, or full-time vs. part-time status can also trigger an amendment.

Step 2: Update payroll for FICA withholding

Here is a tax surprise that catches many finance teams. Students on F-1, including OPT and STEM OPT, who are nonresident aliens for tax purposes are generally exempt from Social Security and Medicare (FICA) taxes. That exemption does not follow them into H-1B status.

Once the employee is an H-1B worker, FICA applies, whether they are a resident or nonresident alien for income tax purposes. Practically, that means:

• Start FICA withholding on wages earned on or after the H-1B start date
• Split the pay period if it straddles the status change
• If the October payroll missed it, correct it fast and work with your payroll provider to collect and remit both the employee and employer shares within the same calendar year

Also flag for your employee that their tax residency picture may change. Days in F-1 status are often excluded from the substantial presence test, while H-1B days count. A tax professional should review their Form W-4.

Step 3: Close out the STEM OPT training plan

If your employee was on a STEM OPT extension, that period ends early when H-1B begins. The commitments you made when signing the Form I-983 don’t simply disappear.

Here is your cleanup list:

1. Final evaluation: Complete the final I-983 evaluation covering the time since the last evaluation through the last day of STEM OPT. The employee does a self-evaluation, and the supervisor reviews and signs. It goes to the Designated School Official (DSO) within 10 days after the reporting period ends, so for an October 1 change, the deadline falls in the first half of October.
2. 12-month evaluation: If they were on STEM OPT for more than 12 months, verify it was submitted. If not, complete it now.
3. DSO notice: A switch to H-1B is not a termination, but confirm in writing that STEM OPT ended because of the change of status. This keeps the record clean.
4. Recordkeeping: File the signed I-983, all evaluations and DSO correspondence in the employee’s immigration file.

For employees still in cap-gap, I-983 obligations continue in full until H-1B status actually starts.

What if the H-1B petition is still pending?

Not every cap-subject petition is approved by October 1. Under the H-1B modernization rule effective January 2025, cap-gap extends F-1 status and work authorization until the petition is decided or April 1, whichever comes first. For FY 2027 cases, that date is April 1, 2027.

If the petition is still pending on that date, the employee must stop working unless they have another basis for work authorization, such as a valid EAD.

Our practical advice: if there is no decision by around February 2027, consider upgrading to premium processing with Form I-907. USCIS commits to act within 15 business days, though that action could be a Request for Evidence (RFE). Filing by February leaves room to respond to an RFE and still get a decision before the cap-gap cutoff.

Why you should think twice before an early amendment

Businesses change. Maybe you want to transfer your new H-1B employee to a different office or give them a new role. An amended petition is the proper route. But this year, timing matters more than usual.

The FY 2027 cap season was the first under DHS’s weighted selection rule, effective February 27, 2026. Each registration received one to four entries based on the highest OEWS prevailing wage level (Level I to IV) the offered salary met for that job and location.

That creates a risk pattern USCIS may notice:

• At registration, the worksite is in an area where the salary meets Level III or IV, so the registration gets three or four entries.
• Soon after approval, you file an amendment moving the employee, same salary, to a higher-cost city where that pay only meets Level I or II.

The amendment may satisfy LCA wage rules, but it raises an uncomfortable question: was the original worksite a genuine job offer, or chosen to improve lottery odds? That kind of pattern can invite scrutiny, put the petition at risk of revocation, and complicate future extensions and green card filings.

What to do instead:

• Speak with immigration counsel before relocating, promoting or restructuring a new H-1B employee’s role
• Document the business reason at the time you make the decision
• Consider whether a salary adjustment could keep the same wage level
• For discretionary changes, let a reasonable period pass under the approved terms

Changes that don’t lower the wage level carry far less risk, though they may still need an amendment or new LCA posting.

Frequently Asked Questions

How Orange Law can help

Compliance mistakes after an H-1B approval rarely look dramatic on day one. They often surface later during a Department of Labor investigation, a USCIS site visit, an extension filing, or a green card case. Employers handling H-1B Change of Status cases should ensure that employee records, job duties, work locations, and immigration documentation remain consistent with the approved petition.

Orange Law works with employers to audit new H-1B hires against their petitions, plan amendments when required, and keep STEM OPT and cap-gap cases on track. If you have employees who recently changed status or immigration cases that are still pending, Orange Law is happy to walk through your situation and help you understand the next steps.
