Extension of stay: when to file Form I-539 and what to include

When to file#

Work from your date, not from the calendar. If your I-20 ends May 2028, file by about November 2027. If your program ends exactly on your I-20 date and you are not pursuing OPT, no extension is needed — depart or change status within the departure period. If you are pursuing OPT, read the OPT page first: an I-765 filed by March 18, 2027 removes the need for a separate extension.

Timeline#

1. 001

   Three months before your date, or earlier

   Meet your DSO. Ask for an updated I-20 with the new program end date. Start collecting the documents below and have anything not in English translated.

2. 002

   Six months before your date

   Compile the package, make a complete copy of everything, and file. Use certified mail with tracking, or file online if available for your case.

3. 003

   Two to four weeks after filing

   Expect a Form I-797 receipt notice. Keep it. Use the receipt number to monitor your case online.

4. 004

   While the case is pending

   Maintain F-1 status — keep enrolling, keep complying. Do not travel internationally: departing can abandon the application. Answer any Request for Evidence inside its deadline.

5. 005

   Three to six months after filing

   Allow this long for a decision. If the application is denied, do not overstay.

Step 1 — Forms#

• Form I-539, Application to Extend/Change Nonimmigrant Status. Complete every section, type or print in black ink, sign and date in the signature box, and do not submit blank pages. Use Part 3 (Additional Information) for your supporting statement. Include your USCIS online account number if you have filed before.
• Form I-539 Supplement A, one per dependent, if a spouse or children in F-2 status are extending with you. Each dependent needs their own I-94.
• Form I-539 Supplement B, if you are applying for a change of status rather than a plain extension.

Step 2 — Identity documents#

• Passport biographical page. Make two copies — one for the package, one for your records. The passport must be valid for the whole extension period; if it expires during your program, renew it before filing.
• The entire passport, all pages — visa stamps, U.S. entry and exit stamps, travel history.
• The F-1 visa page, if you have a visa stamp.
• Form I-94, front and back — the current record at the time of filing, showing your admission status and expiration date.
• Any Form I-797 Notice of Action USCIS has sent you — prior approvals and receipts for pending applications.
• A valid government-issued photo ID (driver's licence, state ID, or national ID).

Step 3 — Form I-20 and academic records#

• The current Form I-20, signed by your DSO, showing your name, passport number, program, program end date, SEVIS ID, and academic status. Include previous I-20s if you have extended before — they show the progression and continuity of your program.
• The new I-20 or supplement showing the recommended extension period and the DSO's authorization.
• A letter from your DSO confirming satisfactory academic progress, full-time enrollment, good academic standing, the reason for the extension, and whether it is for continued study or OPT, with the DSO's contact details and signature.
• A transcript (official preferred), no more than a year old, showing courses completed, current enrollment, grades, and academic status.
• A letter from your department or program advisor confirming outstanding degree requirements, the expected completion date, your standing, and the reason for any delay.
• A degree audit or program progress report showing credits completed against credits required.
• Course registration for the current term showing full-time status (minimum twelve credits for undergraduates; graduate minimums vary).

Step 4 — Financial documents#

• Bank statements for the most recent two to three months, showing the account holder's name, account number, and balance. Convert home-country funds to U.S. dollars.
• If a sponsor is paying: a signed Form I-864 Affidavit of Support where applicable, with the sponsor's two most recent tax returns, W-2s or an employment letter, and a statement of financial responsibility.
• Scholarship award letters or certificates of eligibility showing the amount, the period covered, and whether it covers the whole extension.
• Tuition receipts or billing statements for the current term, with proof of payment or a payment plan.
• If self-funded through work: two to three months of pay stubs, an employment letter stating position, salary, and duration, two years of signed tax returns, and two years of W-2s.
• If family-funded: a signed support letter with the family member's employment letter, two to three months of bank statements, and two years of tax returns.
• Housing receipts and other bills showing you are meeting your obligations in the United States.
• A cost-of-living calculation — housing, food, transport, health insurance, books, utilities — showing how your funding covers the extended stay.

Step 5 — Employment and OPT evidence (if applying for OPT alongside the extension)#

• A job offer letter on company letterhead showing title, start date, salary, and duration, confirming the role relates to your degree — or, if you have no offer yet, evidence of an active job search: applications, interview confirmations, correspondence.
• A current CV.
• STEM OPT eligibility evidence, if applicable: degree conferral letter, proof the degree is a qualifying STEM field, a DSO letter confirming eligibility, and a list of STEM coursework.
• If Form I-765 is filed concurrently: the I-765 receipt and payment receipt.
• If you completed CPT: an employer letter confirming the dates and that the training was in your field of study.

Step 6 — Proof you have maintained status#

• Your full SEVIS record, showing enrollment history, every I-20 issued, and current status.
• Proof of SEVIS fee payment, if required.
• Course registration for every term, showing continuous full-time enrollment with no unauthorized breaks.
• A DSO certification that you remain in F-1 status with no violations and are eligible for an extension.
• Any prior extension approval notice (Form I-797).

Step 7 — Health and insurance#

• Current health insurance: card (both sides), certificate of coverage, and an insurer letter showing your name, policy number, effective dates, and coverage for the extension period.
• Form I-693 medical examination — only if USCIS specifically requests it; it must be done by a USCIS-designated civil surgeon and is valid for two years.
• Vaccination records if your institution requires them.
• A letter from university health services confirming current coverage and no outstanding holds, if available.

Step 8 — Written statements#

• A personal statement or cover letter, one to two pages: why you need the extension, your academic progress and goals, your expected graduation date, and why the extension is reasonable. Put it in Form I-539 Part 3.
• A statement of intent reaffirming that you intend to return home after completing your studies, why you need a U.S. education, and your ties to your home country.
• A program completion plan: remaining coursework, expected completion date for each requirement, anticipated graduation date, and your plan afterwards.
• An explanation of any delay, supported by a letter from your academic advisor, if the program is running past its original timeline.

Step 9 — Dependents (if applicable)#

• Form I-539 Supplement A for each dependent.
• Each dependent's passport (biographical page and all pages), I-94 (front and back), and I-20 if in F-2 status.
• Birth certificates for children and a marriage certificate for a spouse — original or certified copy, translated into English if necessary — plus divorce decrees for any prior marriages.
• Evidence of the family relationship: photos, joint financial documents, and dependents' school enrollment records.

Step 10 — Seals, certifications and translations#

• The I-20 copy should carry an official stamp from the registrar or DSO office. Transcripts and degree audits should carry the school's seal or the registrar's signature — not a bare printout.
• Every institutional letter must be on official letterhead with the writer's full contact details and signature.
• Notarize documents only where required — some affidavits of support and some foreign documents. Check with USCIS.
• Every document not in English must be translated. The translation must be certified by a translator who states competence in both languages and provides their name, address, contact details, signature, and date, together with the statement: "I certify that the attached translation is true and accurate to the best of my knowledge." Include the original with the translation.

Step 11 — Preparing and filing the package#

• Clear, legible copies — both sides where relevant, in colour for passports, IDs and certificates. Letter size (8.5 × 11 in); reduce anything larger. Paper clips only, no staples.
• Copies, not originals — except documents that must be notarized.
• Filing fee: check the current Form I-539 fee and any biometrics fee on the USCIS website before filing; fees change. Pay by check or money order payable to "U.S. Department of Homeland Security," or online if filing electronically. Keep the receipt.
• A one-page cover letter listing every document enclosed, summarizing the request, and giving your contact details, SEVIS ID and I-94 number.
• A document checklist matching the package, with items marked not applicable where relevant and the total page count.
• Order the package: forms; identity; academic; financial; employment/OPT; status; health; statements; dependents; certifications; translations; payment.
• Verify the correct USCIS filing address for your location on the USCIS website — addresses differ by jurisdiction — and use certified mail with tracking. Keep proof of delivery.
• Keep a complete copy of everything you send, in the same order, for at least two years.

Before you seal the envelope#

• Every form signed and dated; every field completed or marked N/A.
• Contact details current — a phone you answer and an email you check.
• Name, passport number, birth date, SEVIS ID and I-94 number consistent across every document, with no spelling errors.
• I-20 current and not expired; passport valid, or renewed before a decision.
• Payment enclosed and correct; filing address verified; cover letter and checklist included.
• Nothing extra — include only documents that are relevant.
