Working as an F-1 Student: On-Campus Jobs and Curricular Practical Training (CPT), Rule by Rule

NEW Published 31 October 2026

What counts as on-campus, the 20-hour limit, when you may start, and how CPT is authorised and connected to OPT.

SECTION 01Two Doors, Two Different Keys

RULE — No off-campus work in the first academic year, except through the training routes. U.S. Citizenship and Immigration Services (USCIS) states it plainly: F-1 students may not work off-campus during the first academic year, but may accept on-campus employment subject to certain conditions and restrictions. After the first academic year, three types of off-campus employment open up: CPT, Optional Practical Training (OPT), and the STEM OPT extension.

The two doors are authorised differently. On-campus employment is a feature of F-1 status itself: USCIS's Handbook for Employers confirms that, subject to certain conditions, F-1 students may work on campus without approval from USCIS until they complete their course of study. CPT is an authorisation your DSO grants for a specific training opportunity, recorded in SEVIS and printed on your Form I-20. Neither door is opened by a job offer alone — the authorisation must exist first, in the right form.

SECTION 02What Counts as On-Campus Employment

"On-campus" is a defined term, not just a description of where a building is. USCIS's Handbook for Employers sets out the qualifying locations — and the test that excludes some campus work:

ADVICE — If a job's category is arguable, ask your DSO first. The bookstore and the construction company can stand metres apart on the same campus; one counts, the other does not. Describe the employer, location and who pays you, and let the school confirm the category before you work a shift.

SECTION 03On-Campus Employment: Hours, Timing and Paperwork

RULE — Twenty hours per week while school is in session. Study in the States, the Department of Homeland Security's student site, states that if you participate in on-campus employment, you may not work more than 20 hours per week when school is in session. USCIS's Handbook for Employers states the same limit, noting one exception: emergent circumstances that DHS announces in a Federal Register notice — an announced event, not something a student or employer can decide.

RULE — Full-time on-campus work during annual vacation, for continuing students. SEVP's summer-employment guidance states that continuing F-1 students participating in annual vacation are permitted to work on-campus full-time — the official basis for fuller schedules in the summer break.

RULE — You may apply up to 30 days before classes start. Study in the States sets the earliest point, and describes a school-based process: to apply, talk to your DSO; if approved, your DSO will provide you with a letter of approval, and you should ask for a similar document from your employer. Those letters are not decoration — they are the documents the same guidance connects to your next step, applying for a Social Security number (Section 08).

RULE — No USCIS approval is needed for on-campus employment. Unlike the routes that involve Form I-765, on-campus work does not go to USCIS: subject to the conditions here, F-1 students may work on campus without approval from USCIS until they complete their course of study — the end point USCIS's handbook ties to your Form I-20 program end date.

ADVICE — Count every hour, across every on-campus job. Treat the 20-hour limit as a total across all campus roles, and keep your own record of shifts.

SECTION 04CPT: What It Is — and What It Is Not

Curricular Practical Training is a training door, not a general work permit. Study in the States' SEVIS Help Hub defines it by features that must all be present together:

• RULE — It is a recognised training format: alternative work/study, internship, cooperative education, or any other type of required internship or practicum offered by sponsoring employers through cooperative agreements with the school.
• RULE — It is an integral part of an established curriculum. Training outside your curriculum — however valuable, however well paid — is not CPT.
• RULE — It relates directly to your major area of study, and your DSO must be able to determine that it does.
• RULE — It occurs before your programme end date on your Form I-20. Training after that date belongs to OPT, not CPT.

USCIS's Policy Manual ends on the same condition: the CPT must be an integral part of an established curriculum. So a CPT request starts with your curriculum, not a job board. And Study in the States notes CPT authorisation is only required when the training is inside the United States — a summer internship in your home country does not need it.

ADVICE — "Integral" is applied through your own school's curriculum and policies, so the same role can be CPT at one school and unavailable at another. Your DSO's reading of your programme is the one that counts.

SECTION 05CPT Eligibility: The Four Tests

Study in the States lists the conditions under which a DSO can authorise CPT for an F-1 student at an SEVP-certified college, university, conservatory or seminary — four tests, all of which must be passed:

If you cannot yet pass Test 1 and no graduate exception applies, the answer is to wait until the year is complete — using on-campus employment, within its limits, meanwhile.

SECTION 06How CPT Is Authorised, Step by Step

CPT has a feature that surprises students expecting a federal application: there isn't one. USCIS's Policy Manual is explicit that no application to USCIS for employment authorisation, and no Employment Authorization Document (EAD), is required for CPT — the student must request authorisation from the DSO instead. Study in the States lays out the sequence:

Three structural features are worth fixing in memory. RULE — One authorisation, one employer, one period. Authorisation is for one specific employer and for a specific period of time. RULE — Multiple authorisations are possible, each separate. A student can have more than one CPT authorisation at the same time, but a separate authorisation is needed for each employer and for each CPT segment — a second employer or a new period means going back through the DSO process. RULE — A cooperative agreement or employer letter underpins it. CPT requires a signed cooperative agreement or a letter from the employer; that agreement is part of the definition in Section 04, not an administrative extra.

ADVICE — Build the DSO's processing time into your timeline. An offer with an ambitious start date is a reason to contact your DSO the same day, not to start and regularise later: if the Form I-20 start date is later than the employer's preferred date, the Form I-20 date is the one you work to.

SECTION 07Part-Time or Full-Time CPT — and the 12-Month Line That Ends OPT

RULE — CPT may be part-time or full-time. USCIS's Policy Manual states that CPT may be part-time or full-time, and its guidance on hours is precise: there is no maximum number of hours placed on CPT in the regulation it cites; instead, the DSO indicates on the Form I-20 that the training is authorised as full-time or part-time. Your CPT's character is therefore what your Form I-20 says it is — which is why the next rule must be tracked against your own record, not estimated from your timetable.

RULE — One year of full-time CPT eliminates OPT eligibility. Study in the States states it in one sentence: one year of full-time CPT eliminates a student's eligibility for OPT. USCIS's Policy Manual gives the rule its edge: an F-1 student who has received 1 year or more of full-time CPT is ineligible for post-completion OPT at the same educational level. Study in the States' OPT guidance adds the counting rules: full-time CPT at a previous school at the same program level counts toward the 12-month total, while CPT at another program level does not affect OPT — and OPT eligibility itself requires that the student has not been authorised for 12 months or more of full-time CPT.

So part-time CPT does not consume the allowance this rule measures; full-time CPT accumulates across schools at the same level, so transferring does not reset the clock; and reaching the line costs OPT at that level outright, rather than reducing it. Every period of full-time CPT is a decision taken with that 12-month line in view.

ADVICE — Keep a running full-time CPT total. Your Form I-20 authorisations are the record — full-time or part-time, with start and end dates. Add up the full-time segments at your current level, including any from a previous school at the same level, and check the total with your DSO before accepting a long full-time placement.

SECTION 08The Social Security Number — and the Two Doors Side by Side

RULE — Paid work or training means applying for a Social Security number. Study in the States states that all students who receive wages from an employer, by working or by participating in a training opportunity, must apply for a Social Security number (SSN). For on-campus employment you will need the DSO approval letter and a letter of approval from your employer (Section 03); for other employment authorisation, the document used instead is your employment authorisation document from USCIS. The SSN application itself is covered in this series' Social Security number guide.

ADVICE — The mistakes that recur. Starting before talking to the DSO; treating any job physically on campus as on-campus employment; term-time hours drifting past 20 across two roles; assuming an internship makes CPT automatic; starting on the employer's date rather than the Form I-20 date; changing CPT employers without a new authorisation; accumulating full-time CPT uncounted. One habit avoids all of them: no work before its authorisation is in your hand.

Official references and verification status

These official references were accessed and checked on 31 October 2026, and this guide's RULE items were verified claim-by-claim against them (record in the accompanying .sources.md file). Two honest limits. First, on hours: the sources state the 20-hour term-time ceiling for on-campus employment directly, and full-time on-campus work during annual vacation for continuing students; for CPT, USCIS's Policy Manual states that no maximum number of hours is placed on CPT and that the DSO records the training as full-time or part-time on the Form I-20 — so this guide prints no hourly threshold for CPT. Second, the detailed F-1 on-campus page that Study in the States links to sits on ICE.gov, outside this guide's two source domains, so on-campus specifics rest on the Study in the States F-1 guide, USCIS's employer handbook and SEVP's summer-employment guidance, all read for this check.
