What Is Form I-20?

What the I-20 Is and Why It Matters

Form I-20, formally titled the Certificate of Eligibility for Nonimmigrant Student Status, is one of the most important documents for international students in the United States. Issued by a Student and Exchange Visitor Program (SEVP)-certified school, the I-20 certifies that a student has been admitted to a full-time program of study and has demonstrated sufficient financial resources to cover tuition and living expenses.

The I-20 serves multiple critical functions: it is required to apply for an F-1 or M-1 student visa at a U.S. consulate, it must be presented to Customs and Border Protection (CBP) officers when entering the United States, and it is the basis for maintaining legal student status throughout the student's academic career. Every time there is a change to a student's program—such as a major change, program extension, or OPT recommendation—a new I-20 is issued.

The form contains the student's SEVIS ID number (beginning with the letter N followed by 10 digits), the school's SEVP certification number, the student's program of study, program start and end dates, and estimated cost of attendance. Page 2 of the I-20 includes a travel endorsement section that the DSO must sign before the student travels internationally.

Key Information on the I-20

The I-20 is divided into several sections containing crucial information that directly impacts a student's immigration status. The top of the form displays the student's name, date of birth, country of citizenship, and SEVIS ID number. Below that, the school's information is listed, including its name, address, and school code. The program section details the level of education (bachelor's, master's, doctorate), the major field of study, and the program start and end dates.

The financial section shows the estimated costs for the academic year and the sources of funding, including personal funds, school scholarships, and sponsor contributions. This section must reflect accurate financial information because discrepancies can lead to visa denial at a U.S. consulate or issues at the port of entry.

For students applying for OPT, the DSO adds an OPT recommendation to the I-20 in SEVIS, which generates an updated I-20 with the OPT endorsement on page 2. This updated I-20 must be included with the I-765 application submitted to USCIS. Without the OPT-endorsed I-20, USCIS cannot process the EAD application.

• SEVIS ID number (N + 10 digits) — your unique student tracking number
• Program start and end dates — determines OPT eligibility windows
• School code and SEVP certification — verifies school authorization
• Financial information — required for visa issuance and port of entry
• OPT/CPT endorsement — required for work authorization applications
• Travel signature — must be valid (within 6 months for active students, 12 months for OPT)

When You Receive a New I-20

Students receive a new I-20 any time there is a material change to their SEVIS record. Common triggers include initial admission to a school, transfer between SEVP-certified schools, change of academic major or degree level, program extension beyond the original end date, change in funding source, and OPT or CPT authorization. Each new I-20 reflects the updated information in SEVIS.

When transferring between schools, the new institution issues a transfer I-20 once the SEVIS record is released to them. The transfer process must be completed within a specific timeline, and students should work closely with DSOs at both institutions to ensure continuity of status. Failure to complete a transfer properly can result in a terminated SEVIS record.

For STEM OPT extensions, the DSO issues a new I-20 with the STEM extension recommendation, which includes the employer information and the E-Verify company number. This I-20 must be submitted with the I-765 STEM OPT extension application to USCIS.

Safeguarding Your I-20

Immigration attorneys and DSOs strongly advise students to retain every I-20 they have ever received. Historical I-20 forms may be needed for future immigration applications, including H-1B petitions, green card applications, and re-entry to the U.S. after travel. Lost I-20 forms can be reprinted by the issuing school, but this may take time and the school is only required to maintain records for a limited period after the student's program ends.

Students should also ensure that their I-20 travel endorsement signature is current before any international travel. For students in active status, the travel signature is valid for one year. For students on OPT, it is valid for six months. Traveling with an expired travel signature can result in being denied boarding or entry to the United States.

Digital copies of all I-20 forms should be stored securely as backup. While a digital copy is not a substitute for the original document, it can help facilitate requests for reprints and serve as a reference for the information contained in each version.
