US immigration law separates “change of status” (stay inside the country and switch nonimmigrant classes through USCIS) from getting a new visa stamp abroad and seeking admission at a port of entry. Form I-539 is the usual vehicle for many personal and student changes. Employer-sponsored worker changes often run on Form I-129 instead. Confirm your current class and end date on the I-94 record before you choose either path.
When can you change status with Form I-539?
Eligibility hinges on lawful admission, maintaining status through filing, and qualifying for the new classification. USCIS will not approve a change if you already violated status in a way that bars the benefit, or if another rule requires you to depart and reenter in the new class.
For a B-2 to F-1 example, Study in the States and USCIS student guidance expect you to:
- Gain admission to a Student and Exchange Visitor Program (SEVP)-certified school.
- Receive an initial Form I-20 marked for change of status from the designated school official.
- Pay the I-901 SEVIS fee.
- File Form I-539 (online or by mail) with the I-20, financial proof, passport and I-94 evidence, and any biometrics USCIS schedules.
Do not enroll in a full course of study while still in B-1/B-2 status. Starting classes before approval is a classic status violation that can sink both the change and any later extension of stay.
What goes wrong if you leave and reenter?
USCIS policy for F-1 change-of-status applicants is blunt: if you travel abroad while the Form I-539 change is pending, USCIS treats that change-of-status application as abandoned. There is generally no refund. After abandonment you typically need a new I-20, SEVIS fee proof if required again, and an F-1 visa interview at a US embassy or consulate (unless you are visa-exempt), then admission by CBP as a student.
Even after an approved change of status, leaving can force you onto the consular track for the visa stamp that matches the new class. Reentry timing for F-1 students is also tight: you generally may not be admitted more than 30 days before the I-20 program start date. If processing delays push the start date, ask the school to defer the I-20 rather than beginning studies early in the wrong class.
Pending immigrant cases are a different universe. Adjustment applicants often need advance parole (requested on Form I-131) before international travel, which is not the same product as a nonimmigrant I-539 change. Permanent residence steps live on Apply for permanent residence, and medical screening for those cases follows Immigration medical exam rules, not visitor paperwork.
Keep notices reachable through Login.gov accounts and USCIS address updates. If USCIS denies the change, you must leave when your current authorized stay ends unless another lawful option exists.
Common misconceptions
Assuming a B-1/B-2 visa stamp plus a school acceptance letter lets you start classes fails. You need either an approved change of status or admission in F-1/M-1 after consular processing.
Assuming a quick weekend trip abroad “pauses” a pending I-539 safely also fails. Departure usually abandons the change-of-status request.
Summary
Change of status inside the United States is a USCIS Form I-539 decision tied to your current lawful class and end date, not a school enrollment alone. File while still in status, wait for approval before new activities, and treat any international trip during a pending change as a likely abandonment that shifts you to visa and reentry processing.
