CPT vs OPT in the USA: Complete Guide

Curricular Practical Training (CPT) and Optional Practical Training (OPT) are essential opportunities for international students aiming to gain professional experience in the United States. Terms like CPT vs OPT, F-1 student visa, work authorization, STEM OPT extension, USCIS, SEVIS, and employment authorization document (EAD) are key to understanding how these processes work for those pursuing higher education and future careers in the U.S. This comprehensive guide explores every aspect of CPT vs OPT, from eligibility and application to differences, benefits, and strategies for maximizing professional opportunities as an international student.

Understanding CPT: Curricular Practical Training

Curricular Practical Training (CPT) allows international students to acquire practical work experience related to their major field of study while enrolled in a U.S. academic program. CPT experiences typically involve internships, cooperative education, or other training that is integral to the curriculum. Authorization is provided by the designated school official (DSO) representing the institution and is reflected on the student’s Form I-20 through the Student and Exchange Visitor Information System (SEVIS).

Key Features of CPT

  • CPT can be part-time (up to 20 hours per week) or full-time (over 20 hours per week).
  • Full-time CPT for 12 months removes eligibility for OPT at that degree level.
  • Employer-specific, meaning the student must secure a job offer before authorization.
  • Must occur before the academic program end date (pre-graduation).

Eligibility Criteria

Candidates must:

  • Hold valid F-1 student status.
  • Complete at least one academic year at a Student and Exchange Visitor Program (SEVP)-certified institution (except for graduate programs requiring immediate CPT)
  • Ensure training is an integral part of the curriculum.
  • Secure a job/internship offer directly relating to their major area of study before requesting CPT.

Guidelines and Documentation

Authorization must come from the DSO, with the opportunity recorded in SEVIS and specified on Form I-20. Common documentation includes a CPT workshop completion certificate, academic recommendation, a copy of present I-20, training description, and employer agreement letter. CPT must be authorized before beginning employment, and multiple CPT experiences can be held simultaneously as long as criteria are met.

Understanding OPT: Optional Practical Training

Optional Practical Training (OPT) enables international students to pursue employment or internships directly related to their field of study, either during their program (pre-completion OPT) or after graduation (post-completion OPT). Approval for OPT comes from the U.S. Citizenship and Immigration Services (USCIS) after endorsement by the DSO.

Key Features of OPT

  • OPT may be undertaken before or after program completion, with a total duration of up to 12 months for each educational level (bachelor’s, master’s, etc.).
  • The STEM OPT extension provides an additional 24 months for certain science, technology, engineering, and math graduates, totaling up to 36 months.
  • Employment under OPT is not employer-specific, as long as it is relevant to the student’s major.
  • USCIS issues an Employment Authorization Document (EAD) before students can begin working.

Eligibility Criteria

Applicants must:

  • Maintain F-1 status and have studied for at least one academic year.
  • Seek employment related directly to their program of study.
  • Not have previously used OPT authorization for the same degree level.

Guidelines and Documentation

DSO recommendation is required before USCIS can issue the EAD. Documentation needed includes passport photos, Form I-765, present passport, I-94 printouts, and a copy of I-20 with OPT recommendation. OPT can be full-time or part-time, but work during sessions must not exceed 20 hours per week.

Major Differences Between CPT and OPT

The STEM OPT Extension

The STEM OPT extension is a unique feature of OPT for graduates from DHS-approved science, technology, engineering, or mathematics programs. It grants an additional 24 months of post-completion work authorization, extending total OPT to 36 months if criteria are met.

STEM OPT Extension Criteria

  • Valid F-1 status.
  • Currently in a valid period of post-completion OPT.
  • Degree awarded from an SEVP-certified U.S. institution in an approved STEM field.
  • Employment with an E-Verify participating employer.
  • Signed Form I-983 training plan between student and employer.

Cap-Gap Extension

For students transitioning to H-1B status, the cap-gap extension bridges the period between the expiration of F-1 status or OPT and the start of H-1B employment. To benefit from the cap-gap, students must have an H-1B petition filed on their behalf before their F-1 or OPT expires. This helps maintain lawful status and work authorization during the gap period

How to Apply for CPT ?

Application steps may vary by institution, but the general framework is:

  1. Contact academic advisor/DSO to determine available CPT programs, eligibility, policies, and sponsoring employers.
  2. Secure an employment offer letter with required details.
  3. Complete and submit the CPT application—commonly via online school portal with supporting documents.
  4. Upon DSO authorization, obtain documentation specifying CPT start and end dates, and share with employer if requested.
  5. Begin work as authorized on Form I-20.

How to Apply for OPT?

Applying for OPT generally involves:

  1. Consulting with DSO or college student advisor regarding OPT eligibility and options.
  2. Requesting the DSO’s recommendation—the DSO updates SEVIS and endorses the I-20 form.
  3. Filing Form I-765 (Application for Employment Authorization) with USCIS, including all supporting documents and applicable fee.
  4. Awaiting USCIS approval (may require 90+ days).
  5. Receiving the EAD and beginning OPT employment on or after the designated start date.

Best Practices for CPT and OPT Success

Successful navigation of CPT and OPT involves proactive planning and collaboration with institutional advisors. The designated school official (DSO) is a key resource, able to interpret rules, ensure eligibility, and guide application processes. Students should regularly attend university-sponsored information sessions, understand university-specific policies, and closely follow application timelines to avoid delays and missed opportunities.

Conclusion

CPT and OPT present powerful pathways for international students to gain hands-on experience, boost employability, and launch successful U.S. careers. Understanding the eligibility criteria, documentation, and application processes for both programs—plus their impact on long-term career plans and transitions like the STEM OPT and cap-gap extension—is crucial for maximizing opportunities. Regular consultation with the DSO and adherence to federal and institutional guidelines are recommended for hassle-free authorization and employment.

Obtaining an F-1 visa is the most difficult task for students who wish to study in the United States. The first step in the entire procedure is scheduling your visa slot, which is getting harder by the day. Because they don’t know how to book an F1 visa slot, they frequently don’t receive the slot. Here are the specifics of an F-1 visa, including what it is, what a visa slot is, what it entails, and how to reserve one.

Explain F-1 Visa?

Foreign students who wish to study in the United States must apply for an F-1 visa. Since this is a non-immigrant visa, the holder must return to their home country at the end of the visa period. An admission letter from a US university recognized by the Student and Exchange Visitor Program (SEVP) is required for application, and the length of your course will determine how long you need a visa.

Requirements for an F-1 visa

For Indian students who want to study in the United States, the following is a comprehensive list of requirements for reserving an F-1 visa slot:

  • Letter of acceptance from an organization recognized by the Student and Exchange Visitor Program (SEVP). A university, college, elementary and secondary school, language training program, vocational and technical school, seminary, or religious training program can all be considered this type of establishment.
  • Candidates must be enrolled in a full-time course at one of these institutions.
  • Applicants must be deeply connected to their homeland. This indicates that they have a reason to go back to India once their course is over.
  • Evidence of candidate ability to support themselves financially while they are in the United States for the duration of the course. Their financial situation should demonstrate that applicants, or their sponsor, are able to pay for their living expenses, tuition, and other expenses while in the United States.

The appointment must schedule with relevant US authorities to be interviewed prior to receiving F1 visa is referred to as “visa slot.” Since more and more Indian students are traveling to the US each year to further their education, the spots fill up fast. Nevertheless, there are not as many US consulates or VACs (Visa Application Centers) in India as there formerly were.

What’s New For Indian Students Looking To Reserve A Slot For An F-1 Visa?

In November 2023, certain modifications were made to the F1 visa slot application procedure. The updates are as follows:

  • When applicants make an appointment or create a profile, they must submit their passport information.
  • Incorrect passport information will result in the rejection of their application. The price will be lost and candidates will have to start over since their slot will be deemed an F-1 denied slot.
  • Students must make a new profile with the accurate passport details if that occurs.
  • Applicants can make an appointment using an earlier profile that contains the accurate passport details.
  • If previous fee receipt is associated with the profile that has incorrect passport information, they will require a new one.

How to Schedule an Appointment for a US Student Visa

This is a detailed instruction on scheduling an appointment for a US visa in India.

  • Apply to any SEVP-approved institution and be accepted. Following acceptance, students will get a Form I-20 from the institute, which they must complete.
  • The Student and Exchange Visitor Information System (SEVIS) is where you pay the Form I-901 fee. The F1 SEVIS cost is currently $350, or approximately ₹29,100. To proceed with your F1 visa application, they must have the receipt from this location.
  • When students complete the DS-160 online application on the Consular Electronic Application Center website, the visa slot booking process begins. Make sure to verify the data applicants are entering and adhere to the directions. A passport-size photo that satisfies the requirements for U.S. visa photos must also be uploaded; it must be in color, taken within the last six months, 2 × 2 inches or 51 x 51 mm, with a simple white or off-white background, a neutral facial expression, typical streetwear, and in JPEG format. Save the generated confirmation number.
  • On the U.S. Visa Information and Appointment Services website for India, register for an account. Students must apply using their original passport number in accordance with the new regulations. The visa application fee is approximately $185, which is equivalent to ₹15,390. This cost is not refundable.
  • After creating a profile, applicants may schedule an appointment for a US student visa by using the “Schedule Appointment” option. It consists of two parts: the first is at the VAC (Visa Application Center), where your photo and biometrics will be taken, and the second is at the US consulate or embassy that is closest to them. Only when a slot becomes available applicants may make a reservation. They will receive a confirmation, which must present to the interview along with further paperwork.

Thus, these are the entire procedures for scheduling a US visa appointment.
