Curricular Practical Training (CPT) for F-1 Students

Curricular Practical Training (CPT) is off-campus work authorization for F-1 students whose job — an internship, co-op, or practicum — is a required or integral part of their degree program. Unlike Optional Practical Training (OPT), CPT is authorized entirely by your school's Designated School Official (DSO), who notes it in the Student and Exchange Visitor Information System (SEVIS) and issues you a new Form I-20. You do not file anything with U.S. Citizenship and Immigration Services (USCIS) and you do not get a separate Employment Authorization Document (EAD) card for CPT. The single most important number to remember: 12 months or more of full-time CPT makes you ineligible for post-completion OPT at that education level — the OPT you use after graduation, and the gateway to the STEM extension. Because school-specific procedures and federal policy can change, always confirm current rules with your DSO and, for the underlying framework, with U.S. Immigration and Customs Enforcement's Student and Exchange Visitor Program (SEVP) at studyinthestates.dhs.gov and USCIS at uscis.gov.

What CPT is — and what makes it "curricular"

CPT covers "alternative work/study, internship, cooperative education, or any other type of required internship or practicum" that is an integral part of an established curriculum. In practice, that means one of two things must be true:

• The work experience is required for everyone in your degree program to graduate; or
• You are enrolled in a course for the specific term (for example, an internship-for-credit class) that requires the work experience, and you receive academic credit for it.

If neither is true — if the job would simply be a nice resume addition but isn't tied to a course or a program requirement — it does not qualify as CPT. Schools vary somewhat in how they document and structure the "curricular" connection, so ask your DSO or international student office exactly what your school requires (a specific internship course, a learning agreement, a supervisor evaluation, etc.).

In most cases, you must have been lawfully enrolled full-time for one full academic year in F-1 status before you become eligible for CPT. Some graduate programs whose curriculum requires immediate participation in practical training (for example, a program that starts with a mandatory practicum) may be an exception — ask your DSO whether your program qualifies.

Who authorizes it: the DSO, not USCIS

This is the feature that most distinguishes CPT from OPT. For CPT:

• Your DSO reviews your job offer and its connection to your curriculum, authorizes the CPT in SEVIS, and issues you an updated Form I-20 showing the employer, the dates, and whether it is full-time or part-time.
• You must have this new I-20 with the CPT authorization before your first day of work — starting early, even by a day, is an unauthorized-employment violation of your F-1 status. SEVIS will not let a DSO backdate a CPT authorization.
• There is no Form I-765 filing, no separate USCIS fee, and no EAD card. Your work authorization document, for CPT purposes, is the CPT-annotated I-20 itself, which you may need to show an employer for Form I-9 purposes along with your passport, F-1 visa, and I-94 record.

Because CPT authorization is school-based and tied to a specific employer and specific dates, a new job, a new term, or an extension generally requires a new authorization and a new I-20 notation from your DSO — you cannot simply keep working past the end date on the assumption that it will be renewed.

Part-time vs. full-time CPT

CPT can be authorized as:

• Part-time CPT — 20 hours per week or less, generally usable while you are still enrolled in a full course of study during the academic year.
• Full-time CPT — more than 20 hours per week, typically used during official school breaks (like summer) or in programs where the curriculum calls for a full-time work term.

The distinction matters for two reasons. First, if you are doing full-time CPT during an academic term (not a break), your DSO needs to confirm that you remain a full-time student for status purposes, since F-1 status generally requires full-time enrollment unless you qualify for an authorized reduced course load. Second — and more consequentially — the part-time/full-time distinction determines whether your CPT use affects your future eligibility for OPT.

The 12-month rule: CPT's biggest trap

Part-time CPT, no matter how much of it you do, does not affect your eligibility for OPT. But if you accumulate 12 months or more of full-time CPT at a given education level (for example, throughout your bachelor's degree), you become ineligible for post-completion OPT at that same education level — including the 24-month STEM extension that builds on it. The regulation bars post-completion OPT specifically; part-time CPT never affects OPT eligibility.

This rule catches students off guard because it is cumulative and permanent once triggered — it is not a "use it and it resets" allowance. A student who does several full-time co-op rotations, or one long full-time internship year, can unknowingly cross the 12-month full-time threshold and lose post-completion OPT eligibility for that degree, even though a new degree program at a higher level (for example, moving from a bachelor's to a master's) would reset OPT eligibility for the new level. Full-time CPT you used at the same program level — including at a prior school — counts toward the 12-month total; CPT at a different program level does not.

Practical takeaway: before agreeing to a full-time CPT placement, ask your DSO to calculate your cumulative full-time CPT hours to date. If you are close to 12 months, discuss with your DSO whether the placement can instead be structured as part-time, or whether you want to preserve post-completion OPT eligibility for after graduation.

How CPT differs from OPT

Feature	CPT	OPT
Who authorizes it	DSO, via SEVIS and I-20	USCIS, via Form I-765 approval
Work authorization document	CPT-annotated I-20	Employment Authorization Document (EAD) card
Timing	Before graduation, during enrollment	Before and/or after completing studies
Employer connection	Must be tied to a specific curricular requirement or credit-bearing course	Must be directly related to your field of study, but not tied to a specific course
Duration limit	No fixed cap by itself, but 12+ months full-time eliminates post-completion OPT	Up to 12 months per education level (plus up to 24 more for qualifying STEM degrees)
Processing wait	Typically fast — school-internal process	USCIS adjudication time applies; check current processing times on uscis.gov

Because CPT doesn't require a USCIS filing, it is often faster to arrange than OPT — but that speed is exactly why students under-appreciate how permanent the 12-month full-time consequence is.

What to do — steps for arranging CPT

1. Confirm the job is genuinely curricular. Talk to your academic department about whether the position satisfies a degree requirement or needs to be tied to a specific internship course for credit.
2. Get the job offer in writing — employer name, address, supervisor, start and end dates, and hours per week — before approaching your DSO.
3. Meet with your DSO to request CPT authorization. Bring the offer letter and any school-required forms (learning agreement, faculty sign-off, course registration confirmation).
4. Wait for the new CPT-annotated Form I-20 and do not start work before the start date listed on it.
5. Track your cumulative full-time CPT months with your DSO's help, especially if you plan to use post-completion OPT after graduation.
6. Reauthorize for each new term or employer. A CPT authorization is specific to the dates, employer, and (usually) course term listed — a new placement or an extension needs a new I-20 notation.
7. Keep your student status current the whole time — full-time enrollment (unless an authorized exception applies), a valid I-20, and no unauthorized work.

Common mistakes to avoid

• Starting work before the CPT start date on the new I-20. Even one day of early or unauthorized work can be treated as a status violation.
• Assuming an unpaid internship doesn't need authorization. Most unpaid internships tied to a curriculum still require CPT authorization from the DSO; check with your school rather than assuming.
• Losing track of cumulative full-time CPT hours and inadvertently crossing the 12-month threshold before graduation.
• Treating CPT as interchangeable with OPT. They have different authorizing authorities, different documents, and different timing rules — mixing them up in conversations with employers or on Form I-9 can create confusion or delay.
• Dropping or failing the internship-for-credit course that your CPT is tied to. If the academic requirement disappears, so does the basis for the CPT authorization, and continuing to work can become a status violation.

Beware of notario and immigration-consultant fraud

CPT authorization runs through your school's DSO, not through outside "consultants," visa agencies, or notarios — no one outside your school can lawfully authorize or expedite CPT for you, and anyone offering to do so, or to backdate paperwork, or to guarantee a favorable curricular connection that doesn't actually exist, is not a legitimate resource and may be committing fraud. For real questions about your specific program or work authorization, go to your DSO first, and for legal advice about your immigration status generally, consult a licensed immigration attorney or a Department of Justice (DOJ)-accredited representative.
