USCIS Form I-9 – Employment Eligibility Verification

Jurisdiction: Country: United States | Province or State: Federal

USCIS Form I-9 – Employment Eligibility Verification is a federal document used to confirm that a person hired to work in the United States is authorized to do so. It connects your identity with your legal right to work. Every new hire and employer in the United States interacts with this form at the start of employment.

If you are starting a new job, you will complete part of this form. If you are hiring someone, you are responsible for reviewing documents and completing the employer section. The process is required for most paid positions, regardless of citizenship.

This form matters because it helps ensure that employers hire only individuals who are authorized to work under federal law. It also creates a record showing that the employer verified work authorization in a consistent way.

Even though the form is short, it carries significant responsibility. Errors, missing information, or incomplete documentation can create compliance issues for employers and delays or confusion for employees.

Understanding what the form does and how it works helps you complete it accurately and confidently.

What is USCIS Form I-9 – Employment Eligibility Verification?

Clear definition

USCIS Form I-9 – Employment Eligibility Verification is a federally required employment verification document. It confirms two things: your identity and your authorization to work in the United States.

The form is divided into sections. One section is completed by the employee. Another section is completed by the employer. In some cases, additional sections are used for reverification or rehiring.

The form requires the employee to provide personal information and to attest to their citizenship or immigration status. It also requires the employer to physically examine original documents that prove identity and work authorization.

The document is not submitted to the government in most cases. Instead, employers must keep it on file and make it available for inspection if requested by federal authorities.

Who typically uses this form?

Employees complete this form when they are hired for a new job. This includes U.S. citizens, lawful permanent residents, and noncitizens who are authorized to work.

Employers use the form for every new hire. This applies to businesses of all sizes, nonprofit organizations, and certain government entities. The requirement generally applies whether the employee works full-time, part-time, or for a limited duration.

Human resources staff often handle the employer portion in larger organizations. In smaller businesses, an owner or manager may complete the employer section.

Independent contractors typically do not complete this form for the companies they contract with. The requirement usually applies to individuals who are considered employees under federal employment rules.

Why might you need this form?

You need this form when you begin a new job in the United States. Completion is part of the onboarding process.

Employers need it to document that they verified a new hire’s identity and employment eligibility. Without it, the employer may not have proof that they followed federal verification requirements.

You may also encounter the form again if you are rehired by a former employer within a certain timeframe. In some cases, a previous form may be updated rather than creating a new one.

The form may also be used when employment authorization has an expiration date. In those situations, the employer may complete an additional section to reverify continued eligibility to work.

Typical real-life scenarios

• You accept an offer for a full-time office position. On your first day, you are asked to complete the employee section of the form and present acceptable documents. The employer reviews your documents and completes their section within the required timeframe.
• You are hired for a seasonal retail job during the holidays. Even though the position is temporary, the employer must still complete the form because you are an employee receiving wages.
• You are a lawful permanent resident starting a new job after relocating to another state. Even though you have worked in the United States for years, your new employer must complete a new form for this employment relationship.
• You return to a company you previously worked for. Depending on how much time has passed and whether your work authorization has changed, the employer may complete a new form or update the previous one.
• You have temporary work authorization that will expire in the future. Your employer completes the form at hiring and later updates it to confirm that you remain authorized to work.

When would you use USCIS Form I-9 – Employment Eligibility Verification?

You use this form each time a new employment relationship begins. It applies to most hires made after a job offer has been accepted.

For employees, the form is typically completed at the beginning of employment. The employee section is generally filled out no later than the first day of work for pay.

For employers, the form becomes relevant as soon as someone is officially hired. The employer must examine original documentation within a short period after the employee starts working.

The form is commonly used across industries. Office workers, healthcare staff, construction workers, teachers, hospitality employees, and technology professionals all complete this document when hired.

Remote work arrangements also involve this form. Even if an employee works from home, the employer must still verify identity and work authorization through proper document review procedures.

The form may be used again in situations involving rehire. If an employee leaves and later returns, the employer may update or complete a new form depending on timing and prior records.

It is also used when an employee’s work authorization has an expiration date. In that case, the employer may need to reverify authorization before the previous documentation expires.

Legal characteristics of USCIS Form I-9 – Employment Eligibility Verification

This form is required under federal immigration law. Its legal force comes from statutes that prohibit employers from knowingly hiring individuals who are not authorized to work in the United States.

For the form to be effective, it must be completed fully and accurately. The employee must provide complete personal information and sign the attestation. The employer must review acceptable original documents and record the required details.

Common problems include missing signatures, incomplete fields, incorrect document information, and failure to meet timing requirements. Using expired or unacceptable documents can also create issues.

The form must be retained for a specific period tied to the employee’s hire date and termination date. Employers are generally required to store completed forms and make them available for inspection upon request.

Because this is a federal requirement, the rules apply across all states. However, some states may have additional employment verification processes that operate alongside this form. Those state processes do not replace the federal requirement.

This document does not grant work authorization. It only records that the employer reviewed documents that appear to establish identity and employment eligibility. It also does not replace immigration applications, visas, or permanent resident documentation.

The form does not create an employment contract. It does not define job duties, pay, benefits, or length of employment. Its purpose is limited to verification and recordkeeping.

Is it legally binding?

Yes, in the sense that it is a mandatory compliance document under federal law. Both the employee and the employer are required to complete their respective sections truthfully.

When an employee signs the form, they attest under penalty that the information provided is correct. Providing false information can have serious consequences.

When an employer signs the form, they attest that they examined the presented documents and that, to the best of their knowledge, the employee is authorized to work. This signature creates a legal record of the employer’s verification process.

However, the form is not a contract between the employer and the employee. It does not bind either party to continued employment. It simply documents compliance with federal employment eligibility verification requirements.

How to fill out USCIS Form I-9 – Employment Eligibility Verification

Step 1 – Complete the employee information section

If you are the employee, begin by entering your full legal name, including any other names used if required by the form. Provide your current address, date of birth, and other requested identifying information. Fill in each field clearly and accurately. This section is generally completed no later than your first day of employment for pay.

Step 2 – Attest to your citizenship or immigration status

In the employee section, you must select the statement that describes your status. The options typically include U.S. citizen, noncitizen national, lawful permanent resident, or noncitizen authorized to work. If you select a category that requires additional information, such as an alien registration number or expiration date, enter it exactly as shown on your document.

Step 3 – Sign and date the employee certification

After reviewing your entries for accuracy, sign and date the form in the space provided. Your signature confirms that the information is true and correct to the best of your knowledge. The date should reflect when you completed and signed the employee section.

Step 4 – Complete the preparer or translator section if applicable

If someone assisted you in completing the form due to language or other reasons, that person must complete the preparer or translator section. They provide their name, address, and signature. If you completed the form on your own, indicate that no preparer or translator was used, following the form’s instructions.

Step 5 – Present original documents to the employer

After completing your section, present original, unexpired documents that establish your identity and employment authorization. The form provides categories of acceptable documents. You may present documents from one specified list or a combination of other lists, as described in the form’s instructions. Photocopies are generally not acceptable unless specifically allowed.

Step 6 – Employer reviews the documents in person

The employer examines the documents you present. The review is typically done in your physical presence. The employer checks that the documents appear genuine and relate to you. The employer does not determine immigration status beyond reviewing the documents listed as acceptable.

Step 7 – Employer records document information

In the employer section, the employer enters details from the documents you provided. This usually includes the document title, issuing authority, document number, and expiration date if applicable. The employer must record the information carefully and ensure all required fields are completed.

Step 8 – Employer completes employment details

The employer enters the employee’s first day of employment for pay in the designated field. This date is important because it connects the verification process to the start of the employment relationship. The employer also provides the business name and address in the appropriate section.

Step 9 – Employer signs and dates the certification

Once the document review and entries are complete, the employer signs and dates the employer certification section. The signature confirms that the employer examined the documents and believes them to be genuine and related to the employee. The date reflects when the employer completed this review.

Step 10 – Retain the completed form

After both sections are finished, the employer keeps the completed form in its records. The form is not typically sent to a government agency at the time of completion. It must be stored securely and be available for inspection if required under federal rules.

FAQs

Do I need to complete USCIS Form I-9 – Employment Eligibility Verification before my first day of work?

You must complete Section 1 of this document no later than your first day of employment. That means you fill out your personal information and attest to your status on or before the day you start work. The employer completes their portion within three business days after your first day.

What address should I enter if I just moved?

Enter your current physical address where you live at the time you complete Section 1. Do not use a P.O. box. If you move later, you do not update this form for that reason alone, but you should update your employer’s internal records separately.

What if my name on my identity document is slightly different from my current legal name?

You must enter your full legal name in Section 1 exactly as it appears now. If your document shows a prior name, the employer may ask for clarification to ensure the document relates to you. Small differences, like a missing middle name, should be reviewed carefully so the employer can confirm consistency before completing their certification.

Can I choose which documents to present?

Yes. This form includes a list of acceptable documents. You decide which valid document or combination of documents to present from the lists. The employer cannot require a specific document as long as what you present is on the acceptable list and appears genuine.

What happens if my work authorization has an expiration date?

If you indicate that you are authorized to work until a specific date, that date must be entered in Section 1. Before that date passes, the employer must complete the reverification section using updated proof of authorization. If you do not provide renewed documentation in time, you may not be allowed to continue working.

Do I need to attach copies of my documents to this form?

You are not required to attach copies when completing this document unless your employer has a consistent internal policy of copying documents for all employees. The employer records the document title, issuing authority, number, and expiration date directly on the form. If copies are made, they should be kept with the completed record.

What if I make a mistake in Section 1 after I sign it?

If you notice an error, correct it as soon as possible. Draw a single line through the incorrect information, enter the correct information, and initial and date the change. Do not use correction fluid or erase entries, because the record must remain clear and readable.

Is this form filed with a government agency after it is completed?

This document is not routinely submitted to a government office. The employer keeps it on file and must make it available if requested during an inspection. Proper retention and storage are part of the employer’s responsibility under USCIS Form I-9 – Employment Eligibility Verification rules.

What to do after filling out USCIS Form I-9 – Employment Eligibility Verification

• Step 8: Maintain copies of any new employment authorization documents you receive in the future. This helps you act quickly when reverification is required.
