What Is OPT?

Optional Practical Training (OPT) is a period of temporary employment authorization that allows F-1 students to gain practical work experience in their field of study. Post-completion OPT provides 12 months of work authorizationafter you complete your academic program. OPT is not a visa — it is an extension of your F-1 status that permits employment.

If your degree is in a STEM-designated field (as defined by the DHS STEM Designated Degree Program List), you may apply for a 24-month STEM OPT extension, giving you up to 36 months of total work authorization. This makes STEM OPT one of the most valuable benefits of a STEM-designated degree for international students.

For many international students, OPT is the critical bridge between graduation and a longer-term work visa (H-1B) or green card petition (EB-1A, EB-1B, EB-2 NIW). Understanding the deadlines, requirements, and strategic options for OPT is essential.

Who Is This For?

F-1 Students Approaching Graduation

Every F-1 student completing a degree program should understand OPT. It is your primary work authorization after graduation. Plan your OPT application at least 3-4 months before your program end date.

STEM Degree Holders

If your degree has a STEM-designated CIP code, you qualify for the 24-month extension — up to 36 months total. This significantly increases your H-1B lottery chances and gives more time to build your immigration case.

Students Planning H-1B Transition

OPT (especially STEM OPT) gives you up to 3 chances at the H-1B lottery. Use this time strategically — work with your employer to register for the H-1B lottery each March registration period.

Students Building Green Card Cases

OPT is a bridge, not a destination. While on OPT, build your evidence portfolio for EB-1A, EB-1B, or EB-2 NIW. The work experience, publications, and recognition you gain during OPT strengthen your future petition.

How OPT Works

OPT has several components and requirements. Expand each section below to understand the details of standard OPT, the STEM extension, and employer requirements.

Key Deadlines

OPT has strict deadlines. Missing them can mean losing your work authorization entirely. Pay close attention to these dates.

OPT Application Window

Apply for post-completion OPT no earlier than 90 days before your program end date and no later than 60 days after. Missing this window means losing OPT eligibility. Work with your ISSO to file on time.

STEM OPT Extension Filing Deadline

The STEM OPT extension application must be filed before your standard OPT expires. There is no grace period. Start preparing at least 60-90 days before your OPT expiration date to allow time for I-983 completion and processing.

Unemployment Limits

Standard OPT: 90-day aggregate unemployment limit. If you accumulate 90 days of unemployment during your 12-month OPT, your authorization ends.

STEM OPT Extension: 150-day aggregate unemployment limit across your entire OPT period (initial 12 months plus 24-month extension combined). More generous but still requires active monitoring.

Test Your Understanding

What happens if you miss the OPT application window?

STEM OPT Extension

The 24-month STEM OPT extension is available to students whose degree program has a STEM-designated CIP code on the DHS STEM Designated Degree Program List. Here is what you need to know:

How to Check if Your Program Is STEM-Designated

  1. Find your program's CIP code on your I-20 form (check the field of study section)
  2. Compare your CIP code against the DHS STEM Designated Degree Program List(opens in a new tab)Official Source
  3. If your code appears on the list, your program is STEM-designated
  4. If unsure, contact your ISSO or registrar's office for confirmation

What If Your Program Is NOT STEM-Designated?

If your specific program does not have a STEM CIP code, explore these options:

  • Ask about CIP code updates: Some departments have updated their CIP codes. Check if your program recently changed or if there is an alternative CIP code that qualifies.
  • Add a STEM minor or concentration:Some universities allow you to add a STEM-designated minor or concentration that changes your program's CIP code.
  • Consider a dual degree: Pursuing a dual degree with a STEM-designated program may qualify you for STEM OPT.
  • Plan accordingly: If STEM OPT is not available, you have 12 months of standard OPT and one H-1B lottery attempt. Maximize this time by starting your H-1B preparation immediately.

Transition Planning: OPT to Long-Term Status

OPT is temporary. Plan your transition from day one:

  • OPT to H-1B: Your employer registers you for the H-1B lottery each March. STEM OPT gives up to 3 lottery attempts. If selected, H-1B begins October 1. If your OPT expires before H-1B starts, the cap gap extension automatically extends your F-1 status and work authorization. As of January 2025, cap gap extensions now run until April 1 of the relevant fiscal year (previously October 1), providing significantly more transition time.
  • OPT to EB-1A/EB-1B/EB-2 NIW: While on OPT, build your green card evidence portfolio. You can self-petition for EB-1A or EB-2 NIW even while on OPT.
  • Cap-exempt employers: Universities, research institutions, and certain nonprofits are exempt from the H-1B cap. Working for a cap-exempt employer eliminates the lottery requirement.
  • Further education:Starting a new degree program (e.g., PhD after master's) resets your F-1 status and makes you eligible for a new round of OPT after the next program.

Understanding Immigration Intent

Under INA Section 214(b), most nonimmigrant visa holders are presumed to have temporary intent. Understanding how intent rules apply to your visa category is critical when considering green card petitions.

  • F-1 (Student):Non-dual-intent. You must maintain nonimmigrant intent. Filing a green card petition while on F-1 can create complications. However, USCIS has recognized (per Matter of Hosseinpour) that applying for permanent residence does not automatically violate F-1 status.
  • H-1B:Dual-intent visa. You can freely pursue permanent residency while on H-1B without any conflict.
  • O-1:Generally treated as allowing dual intent in practice.
  • J-1:Non-dual-intent. The 212(e) two-year home residency requirement adds additional complexity.

Key takeaway: If you are on F-1 and considering filing an EB petition, consult an attorney first. Transitioning to H-1B before filing a green card petition is often the safer strategy.

What You Should Be Doing NOW

OPT deadlines are strict. Pick the period closest to your stage — your selection is remembered.

Determine if your program is STEM-designated

Check your I-20 for your CIP code and compare it against the DHS STEM Designated Degree Program List. If your program is not STEM-designated, explore options: some universities allow adding a STEM-designated minor, dual degree, or changing concentration. Talk to your ISSO and academic advisor about possibilities.

Apply for OPT within the required window

You must apply for post-completion OPT no earlier than 90 days before your program end date and no later than 60 days after. Work with your ISSO to get a new I-20 recommending OPT, then file Form I-765 with USCIS. Processing times vary — apply as early as possible within the window to avoid gaps in work authorization.

Research employers with E-Verify enrollment and H-1B sponsorship history

If you plan to apply for STEM OPT, your employer must be enrolled in E-Verify. If you are planning for H-1B sponsorship, research employers who have sponsored H-1B visas in the past. The DOL H-1B disclosure database is a useful resource for identifying sponsoring employers.

Meet with your ISSO to plan your OPT timeline

Your International Student and Scholar Office is your best resource for OPT logistics. Schedule a meeting at least 3-4 months before your program end date. They will issue your OPT I-20, answer questions about the application process, and help you understand your reporting obligations.

Common Mistakes

9 mistakes
Avoid these common OPT pitfalls.

Mistake 1

Missing the OPT application window. You must apply no earlier than 90 days before and no later than 60 days after your program end date. Missing this window means losing OPT eligibility entirely. Set calendar reminders well in advance.

Mistake 2

Assuming all STEM department programs are STEM-designated. The STEM designation depends on your specific program's CIP code, not your department name. A 'Data Analytics' program in a business school may not have a STEM CIP code even if the coursework is technical. Always verify your specific program's CIP code.

Questions to Ask

Switch tabs based on who you're consulting.

  • What is my program's CIP code, and is it on the DHS STEM Designated Degree Program List?
  • What is my exact OPT application window? When should I start the process?
  • How long does it typically take to get the OPT I-20 recommendation from your office?
  • If my program is not STEM-designated, are there options to change the CIP code or add a STEM component?
  • What are my reporting obligations during OPT? How do I update my employment information?
  • What happens if I don't find employment before the 90-day unemployment limit?
