Hiring an F-1 Student on CPT: What Employers Should Check Before Day One
By JohnPaul Callan, Immigration Attorney | The Callan Law Firm, P.C.
A company can hire an eligible F-1 student on Curricular Practical Training, but the offer letter is not the work authorization. The student must receive the school's CPT endorsement on Form I-20 before starting, and the employment must fit the authorized dates and conditions.
For an employer hiring its first international intern, the most useful question is: Does the authorization actually cover this company, this work, and this start date? 8 CFR 214.2(f)(10)(i) describes the school-authorized CPT framework.
CPT is authorized by the school
CPT must be an integral part of an established curriculum and directly related to the student's major. The designated school official, or DSO, determines eligibility and records the authorization in SEVIS and on Form I-20. Standard CPT does not require a USCIS-issued EAD.
The employer supports the process with accurate employment information and any letter or cooperative agreement required by the school. A student saying that the school will approve CPT is not a substitute for the issued endorsement. See SEVP's CPT guidance.
Make the offer letter useful to the school
Provide the correct legal employer name, job title, duties, worksite, employment dates, weekly hours, compensation, and supervisor contact information. Use the school's requested format when available.
Describe the actual work. A generic statement that an intern will support the business may not adequately explain its relationship to the student's program. A precise description also gives HR a practical way to check whether a later assignment differs from what was authorized.
Before day one, compare the endorsement against the offer. Resolve a different employing entity, an incorrect start date, or a mismatch in the authorized location or full-time/part-time designation before work begins.
Keep work within the authorized period and hours
Part-time CPT generally means 20 hours or fewer per week; full-time CPT means more than 20 hours. School rules and the actual authorization remain important. Full-time work should not be scheduled under a part-time endorsement.
Put the CPT end date on the company's calendar. An extended internship or a new academic term does not automatically extend the existing authorization. Changes in employer, location, dates, or hours should be reviewed with the student and DSO before implementation.
For instance, a manager who offers an intern two extra weeks of work may view it as a routine staffing decision. HR should first establish whether the current endorsement covers those weeks.
Think ahead before accumulating a year of full-time CPT
One year or more of full-time CPT can eliminate eligibility for post-completion OPT at the relevant educational level. Part-time CPT does not, by itself, have that effect. Review cumulative full-time CPT with the student and DSO before relying on a long internship followed by OPT. The practical-training regulation establishes the one-year limitation.
This is a planning issue, not a reason to avoid qualified candidates. The company should understand which next steps are genuinely available rather than building a staffing plan around assumed OPT eligibility.
Unpaid training and Form I-9 need separate attention
An unpaid internship is not automatically exempt from immigration authorization or labor-law requirements. Ask the DSO and counsel to assess the actual arrangement. Genuine volunteering and an unpaid position at a business should not be treated as interchangeable simply because neither involves a paycheck.
Complete Form I-9 when required and use the current acceptable-document rules. For CPT, USCIS describes a List A combination involving the passport, F-1 admission record, and endorsed I-20. The employee retains the right to choose an acceptable combination. See M-274 guidance for F-1 students.
This guide covers the hiring checks, not every student eligibility or transition issue. Coordinate the student's underlying status, any applicable F-1 transition provisions, and future OPT or STEM OPT employment before the internship ends.
