1) Who Is Eligible for H-4 Status?

H-4 is the dependent classification for certain family members of an H-1B worker. In most cases, the eligible dependents are:

• Spouse of the H-1B principal worker; and
• Unmarried children under 21 of the H-1B principal worker.

Eligibility is not just “family relationship”—you generally also need to show that the H-1B principal is maintaining status (or is being granted an extension/change)
and that the dependent is eligible to follow/extend accordingly.

2) How to Obtain H-4: Inside the U.S. vs. Consular Processing

A) Inside the U.S. (Change of Status or Extension)

If you are in the United States in another valid nonimmigrant status (or already in H-4), you typically request H-4 by filing Form I-539
(and for additional family members, Form I-539A). Many families file the H-1B extension and the H-4 extension/change together to keep timelines aligned.

B) Outside the U.S. (Visa Stamp + Entry)

If you are abroad, you typically apply for an H-4 visa at a U.S. embassy/consulate using the DS-160 process, then enter the U.S. as H-4.
Your admission end date is controlled by the I-94 you receive on entry, which should be consistent with the H-1B principal’s authorized stay.

3) Extensions, I-94 Alignment, and Travel (Common Pitfalls)

In practice, the most common H-4 problems are not “eligibility” problems—they are timing and I-94 alignment problems.
H-4 validity is usually tied to the H-1B principal’s authorized stay, so mismatches can create gaps.

• I-94 end date controls: For many purposes, the I-94 expiration date (not the visa stamp) is what matters inside the U.S.
• Travel during a pending I-539: Departing the U.S. while an H-4 change/extension is pending can create complications. Plan travel around filings when possible.
• Staggered approvals: When H-1B and H-4 are filed together, one can be approved before the other. Your strategy should anticipate that possibility.
• Children approaching 21: If a child is close to turning 21, you should flag it early and build a plan (for example, F-1 or another option) rather than “hope it works out.”

4) Can an H-4 Spouse Work? Understanding the H-4 EAD

H-4 status by itself does not authorize employment. However, some H-4 spouses may qualify to apply for an Employment Authorization Document (EAD)
if the H-1B principal spouse is far enough along in the employment-based green card process. :contentReference[oaicite:1]{index=1}

Who typically qualifies?

• Approved I-140: The H-1B principal is the beneficiary of an approved Form I-140 immigrant petition; or
• AC21 extensions beyond 6 years: The H-1B principal has been granted H-1B extensions beyond the normal 6-year limit under AC21 sections 106(a) and/or 106(b) (commonly tied to a PERM or I-140 that has been pending 365+ days). :contentReference[oaicite:2]{index=2}

The EAD application is typically filed on Form I-765, in the H-4 spouse category (commonly referenced as (c)(26)).
If approved, the authorization is generally not employer-specific (meaning it is not restricted to one employer), but timing and status maintenance are critical. :contentReference[oaicite:3]{index=3}

5) Practical Document Checklist (Most Common Items)

• Passport biographic page(s) and current immigration documents for the H-4 applicant(s)
• Marriage certificate (for spouse) and birth certificate(s) (for children)
• H-1B principal’s approval notice(s) and evidence of current status
• Most recent I-94 records for the H-1B principal and H-4 dependents
• If applying for H-4 EAD: evidence showing the I-140 approval or AC21 extension basis

This list is intentionally general. The “right” evidence depends on whether you are extending inside the U.S., changing status, or applying abroad for a visa stamp.

H-4 FAQs

Can H-4 children work?

H-4 children are not employment-authorized based on H-4 status. If work authorization is needed, families typically explore other strategies well before the child turns 21.

Does an H-4 visa stamp control my stay?

The visa stamp is for entry. Inside the U.S., your authorized stay is typically controlled by the I-94 expiration date.

If my spouse changes H-1B employers, do I have to start over?

Not necessarily, but timelines and approvals can become staggered. The key is keeping statuses aligned and avoiding gaps.

What if we are close to the 6-year H-1B limit?

This is where AC21 and the employment-based green card process matter. Planning early can protect both the H-1B worker and dependent family members.
