Essential Rules and Requirements for F-1 Students on Optional Practical Training
Once your OPT application is approved, there are critical rules you must follow to maintain your F-1 status. This guide covers everything from receiving your EAD card and beginning employment, to travel requirements, reporting obligations, and the consequences of exceeding your allowable unemployment period.

Getting Started with Your EAD
Once USCIS approves your OPT application, you will receive an Employment Authorization Document (EAD). Understanding when and how you can begin working is the first step to a successful OPT experience.
Receiving Your EAD Card
Once your application is approved, USCIS will issue you an EAD. You should make a copy of your EAD and write your UMID somewhere on the page. Scan and email it to your school with a note indicating you applied for OPT and have received your EAD.
Important
Your F-1 status continues through the entire OPT period. You must stop employment when the end date on the EAD card is reached, but you may remain in the U.S. for the 60-day grace period after OPT ends.
When You Can Begin Working
You may begin working once both of the following conditions are met:
- You have physically obtained the EAD card — you may not begin employment if your OPT has been approved but you have not yet received the EAD in the mail.
- The begin date on the card has been reached.
The EAD is not employer-specific, so you may change employers at will. However, employment must be directly related to your field of study. Any employment outside your field of study is unauthorized and constitutes a substantive violation of your status.
Social Security Number
If you do not yet have a Social Security Number (SSN), you will need one for tax reporting purposes. You may apply for an SSN after you have received the EAD card and the begin date on the card has been reached.
Key Points About Your SSN
- If you already have an SSN, do not apply for a new one — Social Security Numbers are for life.
- You do not need your SSN to begin working. On your first day of employment, you may write "applied for" in the space where the SSN is to be provided on employment paperwork.
- Once you receive the Social Security Card in the mail, provide the number to your employer.
Address Notification Requirement
You are required by the U.S. Department of Homeland Security to update your address within 10 days of any change, even while you are on OPT. You can do this online at the USCIS AR-11 portal (www.uscis.gov/ar-11).
Travel Outside the U.S. and Re-Entry
Traveling abroad during OPT requires careful preparation. You must carry specific documents to be re-admitted to the United States as an F-1 student.
Required Documents for Re-Entry
To be re-admitted to the U.S. as an F-1 student, you must present the following documents at the port of entry:
- Your passport, which must be valid for at least six months on the day you re-enter the U.S. If you recently renewed your passport, you may need to carry your old expired passport as well if your F-1 visa is in the expired passport. An exception exists for entering Canada or Mexico only, for no longer than 30 days — this is referred to as Automatic Revalidation of Visa.
- A valid F-1 visa stamp in your passport (except for Canadian citizens). In most situations, the F-1 visa must be valid on the day you enter the U.S.
- Your currently valid I-20 immigration document with a recent handwritten travel signature on page 3. The signature must have been provided by your Foreign Student Advisor after you arrived to begin your study, and it must be less than one year old on the day you re-enter the U.S.
Additional Precautions
You may wish to bring copies of financial documentation and your student transcript as an additional precaution when traveling. If you feel you may come under increased scrutiny, consider obtaining a letter from your department stating that you are a student in good standing with the university.
F-2 Dependents Traveling Separately
If your F-2 dependents travel outside the U.S. and reenter without you during your OPT period, they should carry their own original documents along with photocopies of all the documents you are required to carry for reentry. Refer to the Travel Advisory for the full list of required documents.
OPT Employment Requirements and Reporting
During OPT, you are expected to be employed in your field of study and must report your employment information to SEVIS. Understanding the types of allowable employment and your reporting obligations is essential to maintaining your status.
General Employment Requirements
You are expected to be employed in your field of study during OPT, and you are required to submit employer information to SEVIS. The maximum total period of unemployment allowed is 90 days.
Documenting Your OPT Employment
It is recommended that you keep documentation of all your employment. In the future, you may be asked to provide proof that your employment during OPT was in your field of study.
Specifically, you should maintain evidence for each job including:
- The position held and job title
- Proof of the duration of that position
- Contact information for your supervisor or manager
- A description of the work performed
Pro Tip
If it is not clear from the job description that the work is related to your degree, obtain a signed letter from the employer's hiring official, supervisor, or manager stating how your degree is related to the work you performed. Keep this letter in your personal records.
Types of Employment Allowed During OPT
All OPT employment, including post-completion OPT, must be in a job related to your degree program. The following types of employment are permitted (note: these categories do not apply to students on a STEM extension):
Allowable Employment Types
| Employment Type | Details |
|---|---|
| Paid Employment | May work part-time (at least 20 hours per week) or full-time during post-completion OPT. |
| Multiple Employers | May work for more than one employer, but all employment must be related to the degree program. Pre-completion OPT cannot exceed the allowed per-week cumulative hours. |
| Short-Term Multiple Employers (Performing Artists) | Musicians and other performing artists may work multiple short-term gigs. Must maintain a list of all gigs, dates, and duration, and be prepared to provide evidence if requested by DHS. |
| Work for Hire (1099 Employment) | Contractual work rather than an employment relationship. Workers receive IRS Form 1099-MISC. Must be prepared to provide evidence of contract periods and the contracting company's name and address. |
| Self-Employed Business Owner | May start a business and be self-employed. Must prove proper business licenses and active engagement in a business related to the degree program. |
| Employment Through an Agency | Must provide evidence of working an average of at least 20 hours per week while employed by the agency. |
| Unpaid Employment | May work as volunteers or unpaid interns where this does not violate labor laws. Must work at least 20 hours per week for post-completion OPT and provide evidence from the employer. |
Reporting Employment Changes
Students are required to report changes in employment to their school's Foreign Student Office as soon as possible. It is recommended that you report changes within 10 business days of the change to avoid situations where a DHS official may determine you to be out of status.
Periods of Unemployment
Managing your unemployment time during OPT is critical. Exceeding the 90-day limit can result in a violation of your F-1 status, so understanding what counts as unemployment — and what doesn't — is essential.
Understanding the 90-Day Unemployment Limit
Students on post-completion OPT are only allowed a total of 90 days of unemployment throughout the entire OPT period. This is a cumulative limit, not a consecutive one.
What Counts as Unemployment Time
- Unemployment time is counted each day during the OPT dates indicated on the EAD.
- Students who have OPT extended due to cap-gap provisions continue to accrue unemployment time and remain subject to the 90-day limitation.
- If you have a job offer that begins more than 90 days after your OPT begins, you will exceed your allowable unemployment time. Receiving a job offer within 90 days is not sufficient — you must actually be employed.
- If you travel outside the United States while unemployed, the time spent outside the U.S. still counts as unemployment against the 90-day limit.
- Permanently leaving the U.S. without notifying the International Center can result in accidental accrual of unemployment. You must contact the International Center if you decide to abandon your OPT.
What Does Not Count as Unemployment Time
- Travel abroad while employed — either during a period of leave authorized by an employer or as part of your employment — does not count as unemployment.
- Days of unemployment that occurred before April 8, 2008.
Consequences of Exceeding the Unemployment Limit
- If you exceed the allowable period of unemployment while on post-completion OPT, you are considered to have violated your F-1 status.
Options If You Cannot Find Employment
If you cannot find employment that meets the definition of OPT employment, you may have the following options:
Step 1: Continue Your Education
Apply to your school or another university to continue your education through a change of level or by transferring to another institution.
Step 2: Depart the United States
Leave the U.S. and be sure to notify your school if you abandon your OPT.
Step 3: Change to Another Status
Change status to another legal immigration status, if possible.
