CPT vs OPT: What International Students Need to Know

Understanding CPT vs OPT is essential for F-1 international students who want to gain work experience in the United States. Both programs permit employment related to a student’s field of study, but they serve different purposes and follow different application rules.

Curricular Practical Training is generally used for internships or practical training completed during an academic program. Optional Practical Training can be used before or after graduation and requires authorization from U.S. Citizenship and Immigration Services.

What Is CPT?

Curricular Practical Training, or CPT, is temporary employment or practical training that forms an integral part of an established academic curriculum.

CPT opportunities may include:

• Paid or unpaid internships.
• Cooperative education programs.
• Required practicums.
• Work-study arrangements.
• Training required for graduation.
• Internships that provide academic credit.

CPT must be directly related to the student’s major and authorized by the designated school official, or DSO, before employment begins.

What Is OPT?

Optional Practical Training, or OPT, allows eligible F-1 students to obtain temporary employment directly related to their major field of study.

Students may receive up to 12 months of OPT at each higher educational level, such as:

• Bachelor’s degree.
• Master’s degree.
• Doctoral degree.

OPT is available as pre-completion or post-completion training. Eligible graduates with qualifying STEM degrees may later apply for an additional 24-month STEM OPT extension.

CPT vs OPT: Main Differences

CPT Eligibility Requirements

An F-1 student generally qualifies for CPT when:

• The student has maintained valid F-1 status.
• The training is directly related to the student’s major.
• The position is an integral part of the school’s established curriculum.
• The student has completed at least one full academic year of study.
• The student has received a qualifying job or training offer.
• The DSO authorizes the exact employer, location, and employment dates.
• The student continues meeting the school’s academic requirements.

Graduate students may qualify before completing one academic year when their program requires immediate participation in practical training. CPT is not automatically available simply because an employer offers an internship.

OPT Eligibility Requirements

Students seeking OPT generally need to:

• Maintain lawful F-1 status.
• Complete at least one full academic year.
• Obtain a recommendation from the DSO.
• Submit Form I-765 to USCIS.
• Receive an Employment Authorization Document before beginning work.
• Accept only employment directly related to their major.
• Comply with reporting and unemployment rules.

A job offer is not normally required when applying for standard post-completion OPT. However, students must find qualifying employment before exceeding the permitted unemployment period.

Part-Time vs Full-Time CPT

CPT can be authorized as either part-time or full-time.

Part-Time CPT

Part-time CPT generally means working:

• 20 hours per week or fewer.
• While continuing full-time study.
• Only for the employer and dates shown on Form I-20.

Part-time CPT does not normally reduce the student’s later OPT eligibility.

Full-Time CPT

Full-time CPT generally means working:

• More than 20 hours per week.
• During an authorized academic period or vacation.
• Under the exact conditions approved by the DSO.

Students who accumulate 12 months or more of full-time CPT become ineligible for OPT at the same educational level. Using fewer than 12 months of full-time CPT does not automatically eliminate OPT eligibility.

Pre-Completion OPT vs Post-Completion OPT

Pre-Completion OPT

Pre-completion OPT takes place before the program end date.

Students may generally work:

• Up to 20 hours per week while school is in session.
• Full-time during official school breaks.
• Full-time after completing all coursework when only a thesis or dissertation remains, subject to applicable rules.

Time used for pre-completion OPT is deducted from the 12 months available after graduation. For example, 12 months of part-time pre-completion OPT may reduce post-completion OPT by approximately six months.

Post-Completion OPT

Post-completion OPT begins after the student completes the academic program.

Qualifying employment must:

• Relate directly to the student’s major.
• Total at least 20 hours per week.
• Begin only after the EAD start date.
• Be reported through the school or SEVP Portal.
• Remain within the 90-day unemployment allowance.

Students cannot begin working simply because their OPT application is pending. They must receive the EAD and wait until the authorized start date.

Does CPT Require USCIS Approval?

CPT does not normally require a Form I-765 application or a separate EAD.

The DSO authorizes CPT by entering the employment information in SEVIS and issuing a new Form I-20. The authorization is limited to the:

• Named employer.
• Approved location.
• Specified employment dates.
• Permitted number of weekly hours.

Students must not begin CPT before the authorization start date printed on Form I-20.

Does OPT Require a Job Offer?

A job offer is generally not required when submitting an initial OPT application. The student first receives the DSO recommendation and then applies to USCIS for an EAD.

However, post-completion OPT students must avoid exceeding 90 cumulative days of unemployment.

Qualifying regular OPT employment may include:

• Direct employment.
• Multiple employers.
• Agency or consulting work.
• Certain contract positions.
• Self-employment under appropriate conditions.
• Qualifying unpaid internships or volunteer work.

Every position must be related to the degree, properly documented, and compliant with applicable employment laws.

Can You Use CPT and OPT?

Yes. Many international students use both programs.

For example, a student may:

1. Complete a part-time CPT internship during the second academic year.
2. Complete another CPT internship during summer vacation.
3. Graduate and apply for 12 months of post-completion OPT.
4. Apply for a STEM OPT extension when eligible.

Using CPT does not normally reduce the available OPT period unless the student completes 12 months or more of full-time CPT.

What Is Day 1 CPT?

“Day 1 CPT” is an informal term commonly used for CPT authorized near the beginning of an academic program.

Federal rules allow immediate CPT participation for certain graduate students when the established curriculum requires practical training from the start. However, there is no separate immigration category officially named Day 1 CPT.

Students should be cautious when considering a program that:

• Offers CPT to nearly every student immediately.
• Requires little in-person academic participation.
• Appears primarily designed to provide work authorization.
• Does not clearly explain how employment forms part of the curriculum.
• Allows employment unrelated to the degree.

Improper CPT use can affect future OPT, visa, change-of-status, or immigration applications.

CPT or OPT: Which Is Better?

CPT may be more suitable when:

• You are still completing your degree.
• An internship is required by your curriculum.
• You already have a specific employer.
• You need authorization relatively quickly.
• You want to preserve OPT for after graduation.

OPT may be more suitable when:

• The training is optional rather than required by the curriculum.
• You want to work after graduation.
• You want flexibility to change employers.
• You do not yet have a job offer.
• You want to work for up to 12 months after completing your degree.
• You may qualify for the STEM OPT extension.

The correct option depends on your academic program, employment timing, and long-term career plans.

Common CPT and OPT Mistakes

International students should avoid:

• Starting employment before receiving authorization.
• Working outside the approved CPT dates.
• Changing CPT employers without a new Form I-20.
• Accepting work unrelated to the academic major.
• Assuming an internship is automatically authorized.
• Accumulating 12 months of full-time CPT without considering OPT eligibility.
• Beginning OPT employment before receiving the EAD.
• Failing to report an OPT employer.
• Exceeding the post-completion OPT unemployment limit.
• Relying on advice from an employer instead of consulting the DSO.

Unauthorized employment can result in a violation of F-1 status.
