S3 Blog: Admitted on H-1B or F-2: From Offer Letter to I-539

If you are in the U.S. on H-1B or F-2, you can generally pursue F-1 status through a change of status: get an initial I-20 marked for change of status, pay the I-901 SEVIS fee, and file Form I-539 with USCIS before your authorized stay expires. Keep your current job and status in the meantime. You cannot use F-1 benefits such as CPT until USCIS approves, and whether you can attend classes while pending depends on your current status and the school.

USCIS decides, and decisions can take a long time. Mistakes at this stage (letting a status date pass, quitting a job early, starting practical training too soon) can be hard to repair.

Two ways to become an F-1 student

	Change of status (inside the U.S.)	Consular processing (outside the U.S.)
Decided by	USCIS (Form I-539)	U.S. embassy or consulate
Needs	Initial I-20 marked for change of status; I-901 receipt; I-539	Initial I-20; I-901; DS-160 and visa interview
Result	New status takes effect when USCIS approves	Visa, then admission by CBP at entry
Main risk	Long wait; denial; leaving the U.S. while pending can be treated as abandoning the application	Appointment delays, denial, administrative processing

Step by step
1. Get admitted and receive an initial I-20. The DSO should note “change of status” on the I-20.
2. Pay the I-901 SEVIS fee and keep the receipt. The fee is separate from USCIS filing fees.
3. File Form I-539 before your current authorized stay expires, with the required documents and fees. Use the edition shown on the USCIS page.
4. Consider premium processing if you are eligible. USCIS offers it for change of status to F-1, with a response target of about 30 business days after prerequisites such as biometrics are met. It is a faster processing time, not a guarantee of approval. Regular processing can take months.
5. Wait for the decision while keeping your current status and employment in order.
6. If approved, your F-1 status takes effect on the date of approval. Check in with your DSO immediately.
7. Ask for CPT only after approval. CPT can begin only after USCIS approves F-1 status and your DSO authorizes CPT, on or after the start date shown on your I-20.

For H-1B holders
• Keep the H-1B job and status until USCIS approves. A pending request does not itself authorize F-1 activity.
• If your H-1B employment ends, USCIS regulations allow a discretionary grace period of up to 60 days (or until your authorized stay ends, if sooner). You can use it to file a change of status, but you cannot work during it. A timely, non-frivolous change of status filed within that period generally prevents unlawful presence from accruing while it is pending.
• Ask an attorney how the approval date affects your H-1B work, because your status changes on approval.

One student on our calls was close to the end of the H-1B period and worried about a gap before January classes. The guidance given (to “file for H-1B”) was unclear. What matters is that a change of status is timely filed before the authorized stay ends. For F-1, you do not need to cover the whole period up to 30 days before the program starts, and if USCIS is slow, the school can defer your start date to the next term.

For F-2 holders
The same I-20, I-901 and I-539 steps apply. F-2 is a dependent status, so enrollment while the application is pending is limited (commonly to part-time study) or restricted by school policy. Do not start full-time study until the DSO confirms that your status allows it.

Classes while the change of status is pending
This depends on your current status and your school’s policy:
• B-1/B-2 visitors must not begin studying until approved. Visitors who entered on the Visa Waiver Program (ESTA) cannot change status inside the U.S. at all.
• H-1B, H-4, F-2 and others: some schools allow enrollment, and some do not. The program start date on your I-20 may need to stay in the future while pending, or USCIS may issue a request for evidence.
• Ask the DSO in writing.

What not to do
⚠️ NO CPT BEFORE APPROVAL Do not begin CPT or any F-1 activity until USCIS approves your change of status and the DSO authorizes CPT.
• Do not quit your job before your dates are mapped.
• Do not travel without asking, because leaving the U.S. while pending can affect the application.
• Do not file late. Filing must be made before your authorized stay ends.
• Do not rely on a fixed number of weeks. Processing times are estimates.

Bottom line
Keep your current status and job, file before your authorized stay ends, and do not use F-1 benefits until USCIS approves.
