When a person files a change of status to H-4 and, while that application is still pending, later files an H-1B petition requesting change of status, a confusing situation can arise. The H-1B may be approved first, allowing the person to begin working, and then weeks or months later the H-4 application may also be approved.
At that point, many employers and foreign workers assume that the later H-4 approval automatically overrides the H-1B approval because of what is commonly referred to as the “last action rule.” In reality, the analysis is more nuanced. The controlling status is often determined not simply by which approval notice came last, but by the effective start dates on the I-94 records attached to those approvals.
Understanding this distinction is critical because it affects employment authorization, compliance with employment eligibility verification rules, travel planning, and future immigration filings such as adjustment of status.
A Common Scenario
Consider the following sequence of events, which is increasingly common due to processing delays.
A person is maintaining another nonimmigrant status in the United States. Their spouse later obtains H-1B status, and the individual files a change of status to H-4 using Form I-539. USCIS receives the application and begins processing it, but adjudication takes several months.
While the H-4 application remains pending, an employer files an H-1B petition requesting change of status to H-1B. The employer may use premium processing to speed up adjudication.
USCIS approves the H-1B petition first and issues an approval notice containing an I-94 authorizing H-1B status beginning on a particular date in the future. The beneficiary begins employment in accordance with the H-1B approval.
Weeks later, USCIS adjudicates the earlier-filed H-4 application and issues an approval notice with an I-94 attached.
At this stage, employers and beneficiaries often panic because the H-4 approval notice is dated later than the H-1B approval notice. Many assume that the later approval automatically returns the person to H-4 status.
The key question, however, is not which approval notice was issued later. The critical question is what effective dates appear on the I-94s.
Understanding the Last Action Rule
Immigration practitioners frequently refer to the “last action rule” when analyzing situations where multiple change-of-status approvals exist. In general terms, the rule suggests that the most recent USCIS action that grants an I-94 determines the person’s current nonimmigrant status.
While this shorthand is useful, it can sometimes lead to oversimplified conclusions. The rule is not merely about the chronological order in which approval notices are issued. The analysis must consider the period of authorized stay reflected in the I-94 attached to each approval.
In other words, the operative status depends on which I-94 period is in effect at any given moment.
Why the I-94 Start Date Matters
Each approval notice that grants a change of status includes an I-94 at the bottom of the document. This I-94 contains a start date and an expiration date representing the period during which the individual is authorized to remain in that classification.
If multiple approvals exist, these I-94 periods must be analyzed chronologically.
For example, imagine the following timeline.
The H-4 application is eventually approved with an I-94 showing that H-4 status begins on March 1 of a given year.
The H-1B petition, which was approved earlier, contains an I-94 showing that H-1B status begins on April 15 of that same year.
Even if the H-4 approval notice is issued later than the H-1B approval notice, the effective timeline would be:
March 1 – H-4 status begins
April 15 – H-1B status begins
Once April 15 arrives, the H-1B I-94 becomes the operative status period. From that point forward, the individual is in H-1B status.
The fact that the H-4 approval notice may have been issued later does not necessarily change this timeline, because the H-1B I-94 represents a later effective status period.
Why This Causes Confusion
This situation often creates confusion because people focus on the date printed at the top of the approval notice rather than the dates on the I-94 itself.
A later-dated H-4 approval notice can appear alarming, especially to employers who are concerned about whether their employee remains authorized to work.
However, the approval notice date alone does not determine the controlling status. The correct analysis requires examining the start date and validity period of the I-94 attached to each approval.
If the H-1B I-94 begins after the start date of the H-4 I-94, the H-1B classification will take effect once that date arrives.
Employment Authorization and Employer Concerns
Employers understandably become cautious when they see an approval notice indicating H-4 status issued after an H-1B approval. From an employment compliance perspective, the employer must ensure that the worker remains authorized to work in the United States.
In practice, one mechanism that can provide reassurance in such situations is the employment eligibility verification process.
When an employer runs an employee through the government’s employment eligibility verification system, the system checks immigration status information maintained by the Department of Homeland Security.
If the government’s records indicate that the individual is not authorized to work, the verification process typically returns a mismatch or tentative nonconfirmation.
In situations where overlapping approvals exist, the outcome of the verification process can provide insight into how government systems interpret the individual’s status.
If the verification confirms employment eligibility based on H-1B status, it indicates that the system recognizes the H-1B classification as the operative status despite the existence of a later-issued H-4 approval notice.
This reinforces the principle that the operative status depends on the effective I-94 period rather than simply the order in which approval notices were issued.
How Practitioners Should Analyze These Cases
Whenever overlapping approvals occur, practitioners should follow a structured analysis.
First, gather all approval notices issued by USCIS.
Second, carefully examine the I-94 attached to each approval notice.
Third, construct a timeline showing the start and expiration dates for each I-94 period.
Fourth, determine which I-94 period is operative at the time the analysis is being performed.
This approach avoids incorrect assumptions that can arise from focusing solely on the approval dates printed on the notices.
Why These Situations Are Increasing
Overlapping change-of-status approvals were relatively rare in the past, but they are becoming more common.
Processing times for Form I-539 applications have increased significantly, while employers frequently rely on premium processing for H-1B petitions. This combination often results in the H-1B being adjudicated long before the earlier-filed I-539.
As a result, it is no longer unusual for a later adjudication of an earlier-filed application to occur months after an H-1B approval has already taken effect.
These timing dynamics make it essential for immigration practitioners to interpret multiple approvals carefully.
Key Takeaway
When two change-of-status approvals overlap, the controlling status is not determined simply by the date printed on the approval notice.
Instead, the analysis must focus on the effective start dates and validity periods of the I-94s attached to those approvals.
In many situations where an H-4 approval is issued after an H-1B approval, the H-1B classification will still govern once the H-1B I-94 start date arrives.
For practitioners and employers alike, the lesson is straightforward: always examine the I-94 timeline before concluding that a later approval notice has changed the individual’s status.
