Understanding Work Authorization in the United States
Work authorization is the legal permission granted by the U.S. government.
It allows a non-citizen to accept employment in the country.
In other words, it proves you are eligible to work under federal law.
This authorization is not the same for everyone.
Some people receive it automatically through their immigration status.
Others must apply separately and wait for approval.
Additionally, employers are required by law to verify work eligibility.
They cannot legally hire someone without proper documentation.
Because of this, work authorization protects both workers and employers.
Who Needs Work Authorization Documents USA
Not everyone in the U.S. needs additional work authorization.
However, many people do.
Understanding where you fit is the first step.
You generally need work authorization if you are:
- A non-citizen without permanent resident status
- A student or exchange visitor seeking employment
- An asylum applicant or refugee
- A person with a temporary visa that allows employment
On the other hand, U.S. citizens do not need work authorization documents.
Lawful permanent residents also have automatic permission to work.
Still, they must prove it with valid documents.
Primary Work Authorization Documents USA
There are specific documents recognized by U.S. law.
These documents prove your eligibility to work.
They are used during the hiring process.
The most important ones are explained below.
Employment Authorization Document (EAD)
The Employment Authorization Document is commonly called an EAD.
It is also known as a work permit.
This document is issued by U.S. Citizenship and Immigration Services.
An EAD card shows that you are allowed to work in the U.S.
It includes your photo, name, expiration date, and category.
You usually need an EAD if you are:
- An asylum applicant
- A refugee
- A DACA recipient
- A student on OPT
- In the process of adjusting status
Importantly, an EAD is time-limited.
Therefore, you must renew it before it expires.
Working with an expired EAD is not allowed.
Permanent Resident Card (Green Card)
A Permanent Resident Card is also known as a Green Card.
It proves lawful permanent residence.
At the same time, it grants unrestricted work authorization.
Green Card holders can work for almost any employer.
They do not need a separate work permit.
However, the card must be valid and unexpired.
Because of this, keeping your Green Card current is essential.
Even though the status does not expire, the card itself does.
U.S. Passport or Passport Card
A U.S. passport proves both identity and work eligibility.
It is one of the strongest documents for employment verification.
U.S. citizens can use a passport instead of multiple documents.
This simplifies the hiring process significantly.
However, the passport must be valid.
Supporting Documents Used for Employment Verification
Employers must complete a specific verification process.
This process confirms identity and work authorization.
It is required for every employee.
Form I-9 and Document Categories
Employers use Form I-9 to verify eligibility.
This form requires documents from specific lists.
Documents are divided into:
- List A: Proves identity and work authorization
- List B: Proves identity only
- List C: Proves work authorization only
An employee can present:
- One document from List A
- Or one from List B and one from List C
This system ensures flexibility.
At the same time, it maintains legal compliance.
Social Security Number (SSN)
A Social Security Number is often required for payroll.
It is issued by the Social Security Administration.
However, an SSN alone does not grant work authorization.
It must be combined with legal status that allows employment.
Some SSN cards are restricted.
They may state that work is allowed only with authorization.
Therefore, employers must review this carefully.
Visa Categories That Allow Employment
Some visas include work authorization.
Others require additional approval.
Understanding this distinction is critical.
Employment-Based Visas
Certain visas are designed specifically for work.
These visas tie employment to a specific employer.
Common examples include:
- H-1B for specialty occupations
- L-1 for intracompany transfers
- O-1 for individuals with extraordinary ability
In these cases, work authorization is employer-specific.
Changing jobs usually requires a new petition.
Student and Exchange Visitor Visas
Students often hold F-1 or J-1 visas.
These visas do not allow unrestricted work.
However, employment may be permitted through:
- On-campus work
- Curricular Practical Training (CPT)
- Optional Practical Training (OPT)
Each option has strict rules.
Approval is required before starting work.
How to Apply for Work Authorization
Applying for work authorization involves several steps.
Although the process varies, the structure is similar.
First, you must confirm eligibility.
Then, you submit the correct application.
Finally, you wait for approval before working.
Application Process Overview
Most applicants file Form I-765.
This form requests an Employment Authorization Document.
The process usually includes:
- Completing the form accurately
- Providing supporting documents
- Paying the required fee
- Submitting the application
- Attending biometrics if required
Processing times vary.
Therefore, applying early is strongly recommended.
After Approval
Once approved, you receive your EAD card.
Only then can you legally begin work.
If your card expires, you must stop working.
Renewal should be filed in advance.
This prevents interruptions in employment.
Employer Responsibilities and Legal Compliance
Employers also have legal duties.
They must verify work authorization correctly.
The U.S. Department of Homeland Security oversees enforcement.
Failure to comply can result in penalties.
Employers must:
- Complete Form I-9 on time
- Accept valid documents
- Avoid discrimination
- Retain records properly
This protects workers’ rights.
At the same time, it ensures legal hiring practices.
Common Mistakes to Avoid
Many issues arise from misunderstandings.
Fortunately, they are easy to avoid.
Common mistakes include:
- Working before authorization is approved
- Letting documents expire
- Assuming a visa automatically allows work
- Providing incorrect documents to employers
Being proactive prevents serious problems.
When in doubt, verify before accepting a job.
Renewals, Extensions, and Changes
Work authorization is not always permanent.
Therefore, monitoring expiration dates is crucial.
Renewals may be available.
However, eligibility must still be met.
Additionally, changes in immigration status can affect work rights.
Any change should be reviewed carefully.
This ensures continued compliance.
Why Work Authorization Documents USA Matter
