The h-1b six year limit does not always mark the end of H-1B eligibility. The general rule restricts extensions, changes of status, and readmission after six years in H and L status, but AC21-related provisions create two distinct paths tied to the employment-based green card process. One rests on a PERM application or I-140 petition filed at least 365 days earlier. The other requires an approved I-140 and an immigrant visa number that is unavailable when the H-1B petition is filed.
This article separates those paths and explains the dates that matter. Readers who need the underlying visa framework can begin with our guide to what an H-1B visa is and how it is obtained.
What does the six-year rule actually say?
The federal regulation states that a person who has spent six years in H and/or L status generally may not seek an extension, change of status, or readmission unless the person has resided and been physically present outside the United States during the preceding year. Brief trips for business or pleasure do not satisfy that residence requirement.
Read alone, that provision can sound like a fixed endpoint. The same regulatory structure, however, recognizes separate circumstances in which an employment-based immigrant case can support additional H-1B time. These provisions differ in what must have been filed, whether approval is required, and the length of the extension increment.
Our broader H-1B to green card guide explains where PERM and Form I-140 fit in the overall process. Here, the narrower question is what happens when the six-year point and the immigrant case overlap.
Two paths beyond the h-1b six year limit
| Issue | 365-day filing path | Per-country limit path |
|---|---|---|
| Core condition | A PERM application or I-140 petition was filed at least 365 days before the exemption begins | An approved I-140 exists and an immigrant visa number is unavailable when the petition is filed |
| Filing or approval | Filing can be sufficient | I-140 approval is required |
| Extension increment | One year at a time | Up to three years |
| Current H-1B status | Depends on the provision and requested procedure | The regulation does not require current H-1B status |
This comparison is an initial sorting tool, not an eligibility decision. The filing history, current disposition of the underlying case, and requested H-1B start date all matter.
When does the 365-day clock begin?
The one-year extension provision is tied to the filing of a labor certification application or an I-140 immigrant petition, an authority created by the American Competitiveness in the Twenty-First Century Act of 2000. The relevant milestone is filing, not approval. The qualifying filing must precede the requested exemption start date by at least 365 days.
That distinction can matter when the underlying case remains pending. A decision does not necessarily have to be issued before the H-1B request, but there must be an actual qualifying filing. Planning to file in the future, beginning recruitment, or preparing supporting materials does not substitute for a filed PERM or I-140.
A useful timeline review includes:
- The filing date shown on the PERM or I-140 record
- The amount of H and L time already used
- The requested start date for the new H-1B period
- Any denial, revocation, expiration, or other decision affecting the underlying filing
The exact sequence matters. A person may have an employment-based green card case and still miss the required interval for a particular requested start date.
When can the one-year extension basis end?
The 365-day provision is not an indefinite benefit detached from the underlying immigrant case. Its availability can end when the labor certification expires, when the labor certification is denied or revoked, when the I-140 is denied, or when another terminating event identified in the rule occurs.
An earlier one-year extension therefore does not guarantee that the same basis remains available for a later petition. The underlying filing must still support the request at the relevant time. Our H-1B service page provides an overview for cases in which nonimmigrant status and an employment-based immigrant process must be reviewed together.
Who may request up to three years?
The second path applies when the beneficiary has an approved I-140 but an immigrant visa number is not available on the date the H-1B petition is filed. This provision permits an extension of up to three years.
It has two clear elements:
- The I-140 must be approved, not merely filed or pending.
- The immigrant visa number must be unavailable under the applicable category and per-country limitation when the H-1B petition is filed.
This article does not interpret a particular month’s Visa Bulletin. The legal condition is tied to visa availability on the filing date. The provision also says that current H-1B status is not required. That statement addresses the status prerequisite for this exemption; it does not erase other procedural or immigration-history questions that may exist in a particular case.
How early may the petition be filed?
For the 365-day path, an H-1B petition may be submitted up to six months before the requested start date. The petition can be filed before the full 365 days have elapsed, provided the qualifying PERM or I-140 will have been filed at least 365 days before the exemption period begins.
This creates two dates that should not be confused: the date USCIS receives the H-1B petition and the date the requested extension period begins. A timeline that considers only the petition filing date may overlook the rule’s forward-looking structure.
The city where a person lives does not change this federal analysis. For practical local information, readers in the area can consult our San Jose immigration guide.
What should a timeline review cover?
As the sixth year approaches, the H-1B expiration date should not be reviewed in isolation. A focused document check asks:
- Has all time in H and L status been counted accurately?
- Are any relevant periods outside the United States documented?
- On what date was the PERM application or I-140 petition filed?
- Is the I-140 approved, pending, denied, or otherwise affected?
- Was an immigrant visa number available on the H-1B filing date?
- Has the supporting PERM or I-140 lost its ability to serve as a basis?
- Does the requested start date satisfy the 365-day interval?
These questions help identify which regulatory path, if any, fits the record. Each answer should be confirmed against the actual notices and filings.
This timeline keeps the h-1b six year limit analysis tied to the correct exemption rather than to a general green card filing history.
Frequently asked questions
Must a person leave the United States when six years end?
The general rule conditions a new extension, change of status, or readmission on residence and physical presence abroad during the preceding year. A qualifying AC21 exemption may allow additional H-1B time without relying on that general reset rule.
Can a filed PERM support an extension without an approved I-140?
It can under the 365-day provision if the qualifying filing predates the exemption start date by at least 365 days and continues to provide a valid basis. Approval is not the trigger for that path.
Is a pending I-140 enough for the three-year path?
No. The per-country limit provision requires an approved I-140, along with an unavailable immigrant visa number on the H-1B petition’s filing date.
Is current H-1B status required for the per-country limit exemption?
The regulation expressly states that current H-1B status is not required for that exemption. Other status and procedural issues may still require separate analysis.
May the petition be filed before 365 days have passed?
Yes, in the circumstances described by the advance-filing rule. The petition may be filed up to six months before the requested start date if the qualifying filing will be at least 365 days old when the exemption period begins.
Conclusion
The h-1b six year limit is a decision point, not necessarily a universal endpoint. A one-year extension path can arise from a qualifying filing made at least 365 days earlier, while an approved I-140 and unavailable visa number can support a request for up to three years. Keeping the filing date, approval status, visa availability, and requested start date on one timeline is essential to identifying the correct provision.
