When navigating the US immigration system, two documents come up repeatedly: the work permit and the green card. While both allow you to work legally in the United States, they serve fundamentally different purposes and come with vastly different rights, limitations, and implications for your future in America.
The Short Answer
A work permit (EAD) is temporary permission to work in the US—it expires and must be renewed. A green card grants permanent residence, letting you live and work in America indefinitely and eventually become a citizen. Think of the EAD as a temporary pass; the green card is your permanent membership.
Understanding the distinction between these two documents is critical for making informed decisions about your immigration journey. This guide explains exactly what separates a work permit from a green card, who qualifies for each, and how to determine which path makes sense for your situation.
What’s the Difference? The Core Distinction
| Aspect | Work Permit (EAD) | Green Card |
|---|---|---|
| What It Is | Temporary work authorization document | Permanent resident status + work authorization |
| Duration | 1-5 years (now max 18 months for most) | Card valid 10 years; status is permanent |
| Renewal Required? | ✓ Yes – Must renew before expiration | Card only – status never expires |
| Work for Any Employer? | ✓ Yes – During validity period | ✓ Yes – Permanently |
| Travel Abroad Freely? | ✗ No – Needs Advance Parole | ✓ Yes – With some limitations |
| Path to Citizenship? | ✗ No – Not directly | ✓ Yes – After 3-5 years |
| Sponsor Family? | ✗ No | ✓ Yes – Spouse & children |
| Risk of Status Loss | Higher – If renewal delayed or denied | Lower – Permanent unless revoked |
| Filing Fee | $470-520 (per application) | $1,440+ (one-time for adults) |
The fundamental difference comes down to one word: permanence.
A work permit—officially called an Employment Authorization Document (EAD)—is a temporary document that allows certain non-citizens to work legally in the United States for a specific period. It does not grant you the right to stay in the country permanently, nor does it provide a path to citizenship on its own. An EAD is always tied to an underlying immigration status or pending application, and when that status ends, so does your work authorization.
A green card—officially called a Permanent Resident Card (Form I-551)—grants you the right to live and work in the United States permanently. It’s not just a work permit; it’s proof of your status as a lawful permanent resident. With a green card, you can work for any employer, travel freely, and eventually apply for US citizenship.
Think of it this way: an EAD is permission to work while you’re here temporarily or waiting for something else. A green card is permission to stay and build your life in America permanently.
Valid for limited period (typically 18 months to 2 years); must be renewed
Depends on visa, pending application, or special program (DACA, TPS, etc.)
Authorizes employment but doesn’t grant residence rights or path to citizenship
Requires separate Advance Parole document to travel and return
Live and work in the US indefinitely; card renewed every 10 years but status is permanent
Not tied to employer or visa; you’re a permanent resident of the United States
Eligible to naturalize after 3-5 years; can vote after becoming citizen
Can petition for spouse and unmarried children to get their own green cards
What Is a Work Permit (EAD)?
An Employment Authorization Document is a wallet-sized card issued by US Citizenship and Immigration Services (USCIS) that proves you’re legally allowed to work in the United States. The card includes your photo, name, and an expiration date—because unlike a green card, an EAD is always temporary.
Who Can Get an EAD?
Work permits are available to people in various immigration situations. The most common categories include:
Pending Green Card (C09)
Filed I-485 for adjustment of status; work while waiting for green card decision
H-4 Visa Holders
Spouses of H-1B workers with approved I-140 or extension beyond 6 years
L-2 Visa Holders
Spouses of L-1 intracompany transferees; eligible without conditions
F-1 Students (OPT)
Optional Practical Training after completing degree; STEM can extend to 3 years
Asylum Applicants
Pending asylum cases and those granted asylum or withholding of removal
TPS & DACA
Temporary Protected Status holders and DACA recipients
Pending Green Card Applicants (Category C09): If you’ve filed Form I-485 to adjust your status to permanent resident, you can apply for an EAD to work while your green card application is pending. This is often called a “green card-based EAD” because it’s directly linked to your ongoing green card process.
Spouses of Work Visa Holders: Certain dependent visa holders can obtain work authorization. H-4 visa holders (spouses of H-1B workers) may apply for an EAD if the H-1B holder has an approved I-140 or has received an H-1B extension beyond six years. L-2 visa holders (spouses of L-1 intracompany transferees) are eligible for EADs without additional conditions. E-1/E-2 dependent spouses may also qualify.
Students on Optional Practical Training (OPT): F-1 visa holders can apply for an EAD to work in their field of study after completing their academic program. STEM graduates may qualify for a 24-month extension.
Asylum Applicants and Asylees: Those with pending asylum applications or granted asylum status can obtain work authorization.
DACA Recipients: Individuals granted Deferred Action for Childhood Arrivals can work with an EAD.
TPS Holders: Beneficiaries of Temporary Protected Status from designated countries can obtain work permits.
EAD Validity Periods
Work permits are issued for limited periods, and the validity depends on your category:
December 2025 Policy Change: EAD Validity Reduced
USCIS now limits EADs to 18 months maximum (down from 5 years) for green card applicants, asylum seekers, and refugees. This means more frequent renewals, higher cumulative costs, and greater risk of work authorization gaps. File renewals at least 120-180 days before expiration.
- Adjustment of status applicants: As of December 2025, EADs for green card applicants are now issued for a maximum of 18 months (reduced from the previous 5-year validity)
- H-4 EADs: Typically valid for the duration of the H-1B holder’s status or until the I-140 is no longer valid
- OPT EADs: 12 months for standard OPT; up to 36 months total for STEM OPT
- Asylum-based EADs: Now limited to 18 months under the December 2025 policy change
When your EAD expires, you must apply for renewal—there’s no automatic extension, and working with an expired EAD means working without authorization, which can have serious immigration consequences.
Current EAD Processing Times and Fees
As of early 2026, EAD processing times vary significantly by category:
- Adjustment of status EADs: 2 to 3 months (fastest since 2017)
- H-4 EADs: 4 to 12 months
- OPT EADs: 2 to 4 months for online filers
- Asylum-based EADs: 3 to 9 months
Filing fees (as of January 2026):
- Online filing: $470
- Paper filing: $520
- Adjustment of status applicants filing concurrently with I-485: $260 (reduced fee)
- Asylum applicants and refugees: $0 (fee exempt)
What Is a Green Card?
A green card (Form I-551) is proof that you are a lawful permanent resident of the United States. Unlike an EAD, which only authorizes work, a green card grants you the right to:
- Live permanently anywhere in the United States
- Work for any employer without restrictions
- Travel internationally and return (with some limitations on extended absences)
- Sponsor certain family members for their own green cards
- Access federal benefits and programs
- Apply for US citizenship after meeting residency requirements
The term “green card” comes from the card’s historically green color, though modern versions have incorporated other colors and security features.
Green Card Categories
There are two main pathways to a green card: family-based and employment-based.
Family-Based Green Cards:
- Immediate Relatives of US Citizens: Spouses, unmarried children under 21, and parents of adult US citizens. No annual limit on visas; typically the fastest category.
- F1: Unmarried adult children of US citizens
- F2A: Spouses and unmarried children under 21 of green card holders
- F2B: Unmarried adult children of green card holders
- F3: Married adult children of US citizens
- F4: Siblings of adult US citizens
Employment-Based Green Cards:
- EB-1: Priority workers (extraordinary ability, outstanding professors/researchers, multinational executives)
- EB-2: Professionals with advanced degrees or exceptional ability
- EB-3: Skilled workers, professionals, and other workers
- EB-4: Special immigrants (religious workers, certain government employees)
- EB-5: Immigrant investors
Green Card Processing Times
Green card timelines vary dramatically based on category and country of birth:
Immediate Relatives of US Citizens: Approximately 10 to 14 months for adjustment of status cases; no visa backlog wait.
Family Preference Categories: Wait times range from 2 to 24+ years depending on category and country of birth. Applicants from Mexico, Philippines, India, and China face the longest waits due to per-country limits.
Employment-Based Categories:
- EB-1: Currently available for most countries; 1-2 years for India/China
- EB-2: 2+ years for most countries; 10+ years for India
- EB-3: 2+ years for most countries; 10+ years for India
- Total process including PERM labor certification: 3-5 years for most cases
Side-by-Side Comparison: Rights and Benefits
Understanding the practical differences between these documents helps clarify which one you need and what to expect:
The Combo Card: EAD with Advance Parole
When you file Form I-485 for adjustment of status, you can simultaneously apply for both an EAD (Form I-765) and Advance Parole (Form I-131). USCIS may issue these as a single “combo card”—officially a C09P EAD—that serves both purposes.
The “Combo Card” (C09P EAD)
When filing for adjustment of status (I-485), you can apply for both an EAD and Advance Parole. USCIS may issue a single “combo card” that serves both purposes—authorizing work and international travel. However, recent policy changes mean USCIS often processes these separately now, issuing the EAD first.
The combo card allows you to:
- Work legally while your green card is pending
- Travel abroad and return without abandoning your adjustment application
However, recent USCIS policy changes have “decoupled” these applications in many cases. USCIS now often processes the EAD first and issues it separately, then adjudicates the Advance Parole application afterward. This means you might receive work authorization sooner, but you’ll need to wait longer for travel permission.
Processing Time Comparison
| Document Type | Average Processing Time | Key Factors |
|---|---|---|
| EAD (Adjustment Applicant) | 2-3 months | Fastest since 2017; file with I-485 |
| EAD (H-4 Dependent) | 4-12 months | Backlogs; depends on I-140 status |
| EAD (OPT/STEM OPT) | 2-4 months | Online filing is faster |
| Green Card (Immediate Relative) | 10-14 months | No visa backlog; interview scheduling |
| Green Card (Family Preference) | 2-24+ years | Country of birth; visa backlog |
| Green Card (EB-1) | 1-2 years | Premium processing available for I-140 |
| Green Card (EB-2/EB-3) | 3-10+ years | PERM + visa backlog (India/China longest) |
Fees Comparison
When Do You Need Which Document?
Choose This If…📋 Work Permit (EAD)
- You’re on a visa that doesn’t include work authorization
- Your green card is pending and you need to work now
- You’re an F-1 student wanting post-graduation employment
- You have DACA or TPS status
- You’re an H-4 or L-2 dependent who wants to work
- You need a temporary solution while pursuing permanent status
Choose This If…🪪 Green Card
- You want to live and work in the US permanently
- You want security that doesn’t depend on an employer
- You plan to become a US citizen eventually
- You want to sponsor family members for immigration
- You want to travel freely without worrying about re-entry
- Your visa is expiring with no extension path
You Might Need Both (Temporarily)
Many people hold an EAD while their green card is being processed. Once the green card is approved, the EAD becomes unnecessary and automatically expires. The green card itself serves as permanent work authorization—no separate EAD required.
Pro Tip: You May Need Both (Temporarily)
Many people hold an EAD while their green card is being processed. Once the green card is approved, the EAD becomes unnecessary and automatically expires. The green card itself serves as permanent work authorization—no separate EAD required after that.
Common Misconceptions
Key Takeaways
Understanding the difference between a work permit and a green card comes down to recognizing their fundamentally different purposes:
A work permit (EAD):
- Is temporary authorization to work
- Must be renewed periodically
- Is tied to an underlying status or pending application
- Does not grant residence rights on its own
- Does not lead to citizenship directly
- May require Advance Parole for travel
A green card:
- Grants permanent residence and work authorization
- Represents an independent immigration status
- Allows you to live, work, and travel with minimal restrictions
- Opens the door to US citizenship
- Lets you sponsor certain family members
- Card requires renewal every 10 years, but status doesn’t expire
The Bottom Line
For many immigrants, the work permit is a bridge—a temporary solution that allows you to earn a living while pursuing the ultimate goal of permanent residence. The green card is the destination: stable, permanent status that lets you build a life in America without the uncertainty of expiration dates and renewal applications.
Whether you need an EAD now, a green card eventually, or both as part of your journey, understanding what each document provides—and what it doesn’t—is essential for making informed decisions about your immigration future.
⭐ The Bottom Line
A work permit (EAD) is temporary permission to work—it expires, must be renewed, and doesn’t grant residence rights. A green card is permanent status that lets you live and work in America indefinitely, sponsor family, and eventually become a citizen. For many immigrants, the EAD is a bridge; the green card is the destination.
