Internship Agreement Documents: Cross-Checks for US Hiring

A US internship or apprenticeship file holds up when its documents agree: the name on the offer letter matches the identity document, the program named matches what the school confirms, and the dates fit inside the enrollment term and, for an international student, inside the work authorization. Each paper can look fine alone and the file still fail the comparison. This article lists the fields to compare, what a mismatch looks like and what the reviewer does next. Position as of October 2026, United States, federal rules; state law adds requirements.

Three kinds of file

In the United States, an unpaid intern is judged by the "primary beneficiary" test, while a registered apprentice is an employee under a registered apprenticeship agreement. The Department of Labor's Fact Sheet 71 lists seven factors, including whether there is any expectation of compensation, whether the internship ties to the intern's formal education program, whether it fits the academic calendar, and whether the intern displaces paid staff. If the intern turns out to be an employee, the Fair Labor Standards Act requires minimum wage and overtime.

Registered apprenticeships are administered through Apprenticeship.gov, the Department of Labor's portal. Federal law does not require a written agreement for every unpaid internship, but a written agreement is what the reviewer compares against.

The cross-checks, field by field

The useful question is never "is the document there?" but "does this field agree with that field?"

1. Legal name: agreement against ID

Compare the full name on the offer letter or agreement with the identity document used for the I-9. Typical mismatches: a nickname instead of the legal first name, a dropped middle name, a hyphenated surname on one paper only. Ask the person which form is correct, have the paper reissued, and keep the first version in the file. A name that differs between the I-9 and payroll creates trouble later with tax reporting.

2. Date of birth: ID against agreement

Age drives hour limits for minors under federal and state child labor rules. If the agreement says 17 and the ID says 19, one is wrong. The reviewer does not guess; the reviewer asks for a second document and records the answer.

3. Program: agreement against school confirmation

The program, major, class year and whether credit is awarded must match what the registrar or career services confirms. Many employers rely on an enrollment verification; the school can release education records to a third party only as FERPA permits, usually with the student's consent. A "senior" on the agreement against a "junior" on the verification shifts the dates against the academic calendar. Send the gap back to the school; do not fix it yourself.

4. Dates: agreement against enrollment and work authorization

For an F-1 student on Curricular Practical Training, the work must be authorized by the school's designated school official and endorsed on the Form I-20, with the employer and dates shown. Compare the I-20 endorsement with the offer letter: employer name, start date, end date and full- or part-time status. For OPT, compare the start and end dates on the Employment Authorization Document (EAD) with the offer: work cannot begin before the EAD start date. An offer running to August 31 against an EAD ending June 30 is a mismatch, whatever the school says.

5. Employer identity: agreement against state registry

The legal entity named on the agreement should match the Secretary of State record in the state of formation, including entity name, status and registered address. A trade name with no matching registered entity is a warning sign. A registry lookup shows the entity exists and is in good standing; it does not show that the documents supplied are genuine.

6. Pay: agreement against wage law

For an unpaid role, compare the facts to the seven factors above. For a registered apprentice, compare the stated wage progression to the schedule in the registered agreement and to any state minimum wage, which can exceed the federal rate. A stated wage below the schedule is a mismatch to fix before day one.

Employment eligibility sits beside the agreement

Every employee must complete Form I-9, and the employer must examine the original documents within three business days of the start of work. USCIS explains the form and the document lists. An intern who is an employee is covered. E-Verify is a separate, generally voluntary federal system; check state law, because some states require it.

The I-9 shows that the employer examined documents. It does not tell you whether the school enrollment is genuine, and the enrollment letter says nothing about work authorization. Both answer different questions, so both belong in the file. See our guide to the right-to-work check for the mechanics.

What the reviewer does when fields disagree

1. Clerical error. Typo, wrong year. Ask the issuer for a corrected document and keep the first version.
2. Missing information. No end date, missing page. Ask for the page or an addendum.
3. Unexplained conflict. Two sources disagree and no one can explain it. Second reviewer, hold the start date, record the decision and the reason.

Each outcome leaves a dated decision tied to a document version, which is what you show an auditor, a school or the Department of Labor. See also our article on HR document verification and the industry verification guide.

A worked example from summer intake

A Chicago marketing agency offers a summer internship to an F-1 student. The offer letter says "Jon Park", the passport "PARK JONGHYUN", and the I-20 "Jonghyun Park". The nickname on the offer letter is the first fix: the reviewer asks for a reissue under the passport name so the I-9 and payroll match. The offer runs 1 June to 15 August. The I-20 carries a CPT endorsement from 15 June to 31 August for a different employer name.

Two findings block the start, and neither is the employer's to fix: the endorsement belongs to the designated school official, and the start date follows from it. The reviewer records the I-20 as presented, the request sent and the answer received, then repeats the comparison on the corrected form.

Questions people ask

Does a school letter replace the internship agreement?

No. The letter confirms enrollment and often that the internship earns credit. The agreement sets duties, hours and supervision. You need both, with matching dates.

Can we start an international student before the EAD start date?

No. Work cannot begin before the start date printed on the EAD. Hold the start and re-check the card.

What if a student's name changed?

The identity document presented for the I-9 is the reference. Keep proof of the change and make payroll match.

Where an automated check fits

Six comparisons per file, multiplied by dozens of summer interns, is where errors slip in. A validation tool extracts the fields from each document, compares them (name, date of birth, program, dates, employer identifiers) and flags disagreements for a person to resolve. It compares what the documents say with each other; it does not establish that a document is authentic. See the HR solutions page, the security page and pricing.

Frequently Asked Questions

What belongs in an intern file?

The signed agreement or offer letter, an identity document, the Form I-9 with its supporting documents, school confirmation of enrollment for a credit internship, and for F-1 students the I-20 or EAD.

Which mismatch is most common?

Names and dates. A nickname on the offer letter and a period that runs past the enrollment term or the EAD account for most corrections.

Who signs a registered apprenticeship agreement?

The apprentice and the program sponsor, and the agreement is registered with the Office of Apprenticeship or the State Apprenticeship Agency.

Can the start date wait while a mismatch is resolved?

It should. Starting before the paperwork is settled exposes the employer. Close the discrepancy, record it, then set the date.
