One of the most flexible features of the H-1B visa is the portability provision, which allows H-1B workers to change employers and begin working with a new employer as soon as a non-frivolous H-1B transfer petition is filed with USCIS—no need to wait for approval. This feature has been essential for both employer mobility and workforce continuity in high-demand sectors like technology and engineering.
But does this portability benefit extend to other visa categories like L-1, O-1, TN, or R-1? The answer is a clear no. In this blog, we’ll explore:
- When H-1B portability was introduced
- How it differs from the 240-day rule for extensions
- Why portability hasn’t been extended to other nonimmigrant categories
- Whether there has been demand for expanding it—and why USCIS has resisted doing so
- What employers must do for I-9 compliance under H-1B portability
✅ The H-1B Portability Provision: Background and Benefits
📅 When Was It Introduced?
H-1B portability was created under INA § 214(n) as part of the American Competitiveness in the Twenty-First Century Act (AC21), enacted in 2000. This law aimed to reduce job disruption for H-1B workers and offer employers more flexibility in hiring foreign talent without waiting for lengthy petition approvals.
🔹 What Does Portability Allow?
Under 8 CFR § 214.2(h)(2)(i)(H):
- An H-1B worker may begin employment with a new H-1B employer as soon as the new employer files a non-frivolous H-1B petition.
- The H-1B worker must have been lawfully admitted and must not have worked without authorization.
- There is no 240-day limit; the worker can continue until a decision is made (approval or denial), regardless of duration.
This portability provision significantly reduces employment gaps and helps avoid out-of-status issues while waiting for USCIS to adjudicate the new petition.
📄 I-9 Compliance Under H-1B Portability
When a H-1B worker starts work under the portability provision, the employer must comply with I-9 employment eligibility verification rules:
📨 At Time of Hire (Before Receipt Notice Arrives)
- The employer may rely on proof that the petition has been filed (e.g., FedEx/UPS courier receipt or USCIS lockbox confirmation).
- Section 2 of the I-9 can be completed using:
- Unexpired foreign passport (List A)
- I-94 showing current H-1B status (List A)
📬 After Receipt Notice Is Issued (Form I-797C)
- The employer should retain a copy of the USCIS Form I-797C Receipt Notice in the employee’s I-9 file.
- This supports continued work authorization under the portability rule.
✅ Once H-1B Transfer Is Approved
- Update the I-9 by noting the approval notice (Form I-797A) and attaching a copy.
- Annotate Section 2 or 3 of the I-9 with: “H-1B approved [receipt number], valid until [expiry date].”
Maintaining proper documentation at each stage protects the employer in the event of an I-9 audit.
⏳ The 240-Day Rule: Key Difference
While H-1B portability allows indefinite employment while a transfer is pending, the 240-day rule only allows a worker to continue in their current role for up to 240 days after the I-94 expires, if a timely extension petition is filed.
- Found in 8 CFR § 274a.12(b)(20)
- Initially applied to H-1B and a few other categories
- Work must stop at day 241 unless the extension is approved
📆 A Quick Comparison:
| Rule Type | Applies To | Start Work Upon Filing? | Work Limit? |
|---|---|---|---|
| H-1B Portability | H-1B | ✅ Yes | ❌ No fixed limit (until decision) |
| 240-Day Rule | H-1B, L-1, O-1, R-1, etc. | ❌ No (unless already employed) | ✅ 240 days max |
❌ Portability Does NOT Apply to Other Visa Categories
No other nonimmigrant category benefits from H-1B-style portability. If you’re on L-1, O-1, TN, R-1, or E-2, you must wait until USCIS approves the new employer’s petition before starting work. There is no regulatory equivalent to INA § 214(n) for these visas.
| Visa Type | Portability (Work Upon Filing?) | Notes |
| L-1 | ❌ No | Must wait for USCIS approval; no portability allowed |
| O-1 | ❌ No | Must wait for new employer petition approval |
| TN | ❌ No | Must obtain new TN entry or approval |
| E-1/E-2 | ❌ No | Work tied to specific employer/business |
| R-1 | ❌ No | Must wait for USCIS approval before starting |
🚫 Why Hasn’t Portability Been Extended to Other Categories?
💬 Has There Been Demand?
Yes. Over the years, advocates and employers have requested similar portability rules for visa categories like L-1 (for multinational executives), O-1 (for extraordinary ability), and TN (for NAFTA professionals).
⚠️ Why Hasn’t USCIS Allowed It?
USCIS has cited several reasons:
- Lack of statutory authority: Unlike H-1B, which has a specific statute (INA § 214(n)) permitting portability, other categories have no such legislative basis.
- Program-specific integrity concerns: For example, R-1 visas require onsite inspections; L-1 has fraud concerns; E and TN categories are treaty-based.
- Regulatory complexity: Extending portability would require legislative changes or a major rulemaking initiative.
Despite expanding the 240-day rule to more categories via the 2016 DHS final rule (81 Fed. Reg. 82398), USCIS has made no move to create portability across visa types.
📅 Conclusion
H-1B portability remains a uniquely powerful and flexible feature under U.S. immigration law. It allows job mobility and uninterrupted employment for high-skilled foreign workers—something that other visa categories still lack.
While the 240-day rule offers temporary relief during extension filings, it does not match the freedom of H-1B portability. Unless Congress enacts broader reforms or DHS undertakes major regulatory changes, portability will remain exclusive to H-1B holders, despite continued demand from employers and stakeholders in other sectors.
