For thousands of Indian students, the dream of studying in the USA isn’t just about getting a world-class degree it’s also about gaining valuable international work experience. This is where two critical acronyms come into play: OPT and CPT.
Understanding the difference between Optional Practical Training (OPT) and Curricular Practical Training (CPT) is essential for every F-1 visa student. These programs are your legal gateway to working in the US, but they have very different rules, purposes, and timelines.
This guide will break down everything you need to know about OPT and CPT, helping you plan your academic and professional journey in the US with confidence.
What is CPT (Curricular Practical Training)?
Curricular Practical Training (CPT) is a type of work authorization that allows international students to gain practical experience through employment, internships, or co-op programs that are an integral part of their established curriculum.

How the "Curricular" Rule Defines CPT
The key word here is "curricular." CPT is not just any job; it must be a required or credit-bearing component of your degree program. For example, if your Master's in Computer Science program requires a one-semester internship to graduate, that internship would be done on CPT.
Key Features of CPT
- Purpose: To complete a required academic component of your degree.
- Timing: Must be undertaken before you graduate.
- Authorization: Authorized directly by your university's Designated School Official (DSO). You will receive an updated Form I-20. USCIS approval is not required.
- Job Offer: You must have a specific job or internship offer to get CPT authorization.
- Work Hours: Can be part-time (20 hours or less per week) or full-time (more than 20 hours per week).
What is OPT (Optional Practical Training)?
Optional Practical Training (OPT) is a period of temporary employment that is directly related to your major area of study. As the name suggests, it is "optional" and is intended to provide you with real-world work experience.
How "Optional" Training Defines OPT
Unlike CPT, OPT is not tied to your curriculum requirements. It is a separate benefit of your F-1 status. Most students use their OPT period after they graduate to work in the US for one year.
Key Features of OPT
- Purpose: To gain practical work experience in your field of study.
- Timing: Can be done before graduation (Pre-completion OPT) or, more commonly, after graduation (Post-completion OPT).
- Authorization: Recommended by your DSO, but must be formally authorized by the U.S. Citizenship and Immigration Services (USCIS). You will receive an Employment Authorization Document (EAD card).
- Job Offer: A job offer is not required to apply for Post-completion OPT.
- Work Hours: Standard Post-completion OPT is full-time.
CPT vs OPT: Key Differences at a Glance
For a clear overview, here is a direct comparison of the most important features of CPT and OPT.
| Feature | Curricular Practical Training (CPT) | Optional Practical Training (OPT) |
|---|---|---|
| Primary Purpose | Part of your academic curriculum (e.g., required internship) | Practical work experience in your field |
| When to Use It | Before completing your degree | Before or after completing your degree |
| Authorizing Body | Your university's DSO (Designated School Official) | USCIS (U.S. Govt. Agency) |
| Required Document | Updated Form I-20 with CPT authorization | Employment Authorization Document (EAD Card) |
| Job Offer Needed? | Yes, you need a specific job offer to apply. | No, you can apply without a job offer. |
| Total Duration | Varies by program. | Standard 12 months per education level. |
| Impact on Other Training | Crucial: Using 12 months or more of full-time CPT will cancel your OPT eligibility. | Standard OPT doesn't impact CPT. |
| STEM Extension | Not eligible. | Eligible for a 24-month extension (total 36 months). |
OPT and CPT Eligibility: Do You Qualify?
Eligibility for both programs requires you to be in valid F-1 status and to have been lawfully enrolled full-time for at least one full academic year.
CPT Eligibility Checklist for Indian Students
- You have been enrolled full-time for one academic year.
- Your chosen internship or co-op is a required or credit-bearing part of your degree.
- You have a formal job offer letter from an employer.
- Your DSO has approved your training.
OPT Eligibility Checklist for Indian Students
- You have been enrolled full-time for one academic year.
- You have not completed 12 months of full-time CPT.

- You have applied within the correct USCIS timeframes.
The STEM OPT Extension: A 3-Year Advantage
For Indian students in technical fields, the STEM OPT extension is one of the most significant advantages of studying in the US.
What is the STEM OPT Extension?
If you have earned a degree in a designated Science, Technology, Engineering, or Mathematics (STEM) field, you can apply for a 24-month extension of your post-completion OPT. This gives you a total of up to 36 months of work authorization after graduation.
Why the STEM OPT Extension is Crucial for Indian Students
This extended three-year period provides a substantial window to gain deep professional experience. More importantly, it gives you three chances to be selected in the H-1B visa lottery, significantly increasing your prospects for long-term employment in the US if that is your goal. To be eligible, your employer must be enrolled in the E-Verify program.
How to Apply for OPT and CPT: A Step-by-Step Guide
The application processes are very different. CPT is managed by your school, while OPT involves the US government.
Your CPT Application Process
- Secure an Internship: Find and accept a job offer that meets your program's CPT requirements.
- Get the Offer Letter: Obtain a formal offer letter with job details, start/end dates, and location.
- Contact Your DSO: Approach your university's International Student Office. They will guide you on the school's specific CPT application form.
- Receive New I-20: Once approved, your DSO will issue a new Form I-20 with the CPT authorization printed on it. You can only begin working on or after the start date mentioned.
Your OPT Application Process (and crucial deadlines)
Applying for OPT is more complex and has strict deadlines.
- Attend an OPT Workshop: Your university will hold mandatory workshops. Attend one.
- Request OPT Recommendation from DSO: Your DSO will verify your eligibility and recommend OPT in your SEVIS record, issuing a new I-20.
- File Form I-765 with USCIS: You must file Form I-765, Application for Employment Authorization, with USCIS. The filing window is critical: you can apply up to 90 days before your program end date and no later than 60 days after it.
- Receive EAD Card: The process can take 3-4 months. Once USCIS approves your application, they will mail you your EAD card. You cannot start working until you have the EAD card in your hand and the start date on the card has arrived.
Strategic Planning for Your US Career
- Choose Your Program Wisely: When shortlisting universities, look for programs that have strong internship, co-op, or practicum components. This signals good CPT opportunities.
- Connect with Your DSO Early: Your Designated School Official is your most important resource. Build a good relationship with the international student office from your first semester.
- Plan Your Timeline: Do not miss the OPT application window. Mark the dates in your calendar. A late application can cost you valuable time and opportunities.
By understanding the rules of CPT and OPT, you can strategically map out your education and career path, making the most of your incredible journey as an international student in the United States.
OPT and CPT: Frequently Asked Questions (FAQ)
Can I work on CPT and OPT at the same time?
No. They are separate authorizations for different purposes and timeframes.
Does part-time CPT affect my OPT?
No. Using part-time CPT (20 hours/week or less) does not affect your 12-month OPT eligibility. Only accumulating 12 months of full-time CPT will make you ineligible for OPT.
Do I need a job to apply for post-completion OPT?
No, you do not need a job offer to apply for your initial 12-month OPT. However, you are only allowed a total of 90 days of unemployment during this period.
What happens after my OPT ends?
After your OPT (and any extension) ends, you have a 60-day grace period to leave the US, get accepted into a new degree program, or change your visa status (e.g., to an H-1B if a company sponsors you).
