OPT Unemployment Days: The 90-Day and 150-Day Limits
NEW Published 7 November 2026
How the unemployment caps work on post-completion OPT and the STEM OPT extension, what counts as employment, how SEVIS keeps the count, and what happens when the limit is reached.
On post-completion OPT you may not accrue more than 90 days of unemployment in total. If you are granted the 24-month STEM OPT extension, the ceiling for your whole OPT period — post-completion plus STEM — is 150 days: the extension adds 60 days, it does not start a new 150. SEVIS counts from your actual OPT start date and treats every day with no employer information in your record as a day of unemployment, so a job you hold but never report still burns days. Paid work related to your programme stops the clock; on post-completion OPT, volunteering and unpaid internships can also count if they are related to your programme, run at least 20 hours a week and break no labour law — on STEM OPT they cannot. Exceed the cap and you are no longer maintaining F-1 status.
SECTION 01The Two Caps: 90 Days, Then 150 in Total
RULE — Status depends on employment. The regulation at 8 CFR 214.2(f)(10)(ii)(E) opens with the sentence everything else follows from: "During post-completion OPT, F-1 status is dependent upon employment." Unemployment is therefore not a neutral pause in your OPT year — it is a measured exception to the condition your status rests on.
RULE — 90 days on post-completion OPT. The same paragraph sets the first cap: a student "may not accrue an aggregate of more than 90 days of unemployment during any post-completion OPT period." USCIS's Policy Manual states the same limit in the same terms. Note the word "aggregate": separate gaps between jobs add together. The allowance does not reset when you start a new job — it only stops growing while you are employed.
RULE — 150 days across the whole OPT period with STEM OPT. Students granted the 24-month STEM OPT extension "may not accrue an aggregate of more than 150 days of unemployment during a total OPT period, including any post-completion OPT period." USCIS's STEM OPT page presents the same arithmetic as a table: initial OPT allows up to 90 days; the 24-month extension adds 60; the total is 150. So if you used 60 days before the extension begins, 90 remain for the STEM period — not 150.
RULE — The caps cover unemployment, not the OPT period itself. Reaching the end of your authorised OPT period is a separate event from exhausting unemployment days, and the two clocks run independently: your EAD end date does not move because you were unemployed, and your unemployment allowance does not grow because OPT time remains.
SECTION 02How the Count Runs: SEVIS Does the Arithmetic
RULE — The count starts at your actual OPT start date. DHS's Study in the States unemployment-counter guidance explains that SEVIS counts from the Actual OPT Start Date in your record, and counts each day on which there is no employer information as a day of unemployment. The counter displays the days allowed, the days accrued and the days remaining.
RULE — The record is what counts, not the reality. Because the count is built from employer information in SEVIS, employment that exists but was never reported is indistinguishable from unemployment. Study in the States' OPT guidance makes the same point from the other side: employer start or end dates that fall outside your actual OPT dates can make you appear unemployed for days you actually worked. Accurate, prompt reporting (Section 05) is what keeps the official count equal to the true one.
RULE — DSOs are shown who is approaching the line. SEVIS maintains a list of students terminated for exceeding the maximum number of days of unemployment, and DSO-facing alert lists surface students on approved OPT or STEM OPT with accrued unemployment days so schools can follow up. Your DSO can see your count; ask them for it rather than guessing (Section 07).
SECTION 03What Counts as Employment on Post-Completion OPT
RULE — Paid employment related to your programme. The baseline case: work for an employer, related to your programme of study. USCIS states that on post-completion OPT you must work part time (at least 20 hours per week) or full time — work below that intensity does not hold the clock.
RULE — Volunteering and unpaid internships can count, on conditions. USCIS's Policy Manual confirms that a post-completion OPT student "may work as a volunteer or unpaid intern, as long as this practice does not violate any labor laws, and the employment is related to the program of study," and that the student must work at least 20 hours per week. All three conditions — no labour-law violation, related to the programme, at least 20 hours a week — must hold together.
PARTIALLY VERIFIED — The fuller list of employment types. SEVP's OPT policy guidance (Policy Guidance 1004-03) is the document that enumerates the wider menu — payment by multiple short-term employers ("gigs," with a list of engagements, dates and durations kept as evidence), work for hire on a contract basis, self-employment through a properly licensed business related to the degree programme, and employment through an agency with evidence of an average of at least 20 hours per week. That guidance PDF could not be loaded from ice.gov in this check (it returned an access error), and the list was read in verbatim reproductions of the guidance on university sites — so treat these categories as the long-standing SEVP position reproduced in print, confirm any of them with your DSO before relying on one, and keep documentary evidence of hours, contracts and licences either way.
RULE — Whatever the type, it must be related to your programme. Every qualifying category shares the same spine: the work must be related to your programme of study. Work outside your field does not stop the unemployment clock even if it is paid, full-time and lawful in every other respect.
SECTION 04What Counts on STEM OPT: A Narrower Door
RULE — A bona fide employer-employee relationship is required. STEM OPT is built around a formal training plan with a real employer. USCIS's Policy Manual excludes arrangements that are not bona fide employer-employee relationships — its examples include multiple employer arrangements, sole proprietorships, and temp-agency or consulting-firm labour-for-hire structures where the named employer is not the entity actually providing the training.
RULE — No volunteering, no unpaid work, no working for yourself. The Policy Manual is explicit that the employer may not be the student "in name only," and that the student may not work for the STEM employer on a volunteer basis — the direct opposite of the post-completion rule in Section 03. A staffing or temporary agency can employ a STEM OPT student only where the agency itself provides the training and maintains the bona fide employer-employee relationship. Start-ups are not excluded as such, but every requirement — including compensation commensurate with similarly situated U.S. workers — must be met.
RULE — The employer must be enrolled in E-Verify. STEM OPT employment is only possible with an employer enrolled in E-Verify and in good standing, with a valid IRS employer identification number, and the training itself is documented on Form I-983 — the application mechanics are in our STEM OPT application guide, linked below.
SECTION 05Reporting: The Duty That Keeps the Count Honest
RULE — Report changes to your DSO within 10 days. Under 8 CFR 214.2(f)(12)(i) and DHS's OPT guidance, while on OPT you must report any change of legal name or address, and any interruption of employment, to your DSO — Study in the States puts the student's deadline at within 10 days of the change, including employment information. The DSO then updates SEVIS (DHS guidance gives DSOs 21 days to make the update).
RULE — The SEVP Portal helps, but does not replace the duty. Students on OPT can view and update contact and employer information through the SEVP Portal, which is the fastest way to keep the record — and therefore the unemployment count — accurate. On STEM OPT the portal has limits: new employer information must go to your DSO with a new Form I-983, and the six-month validation reports run through the DSO as well; our STEM OPT application guide covers that cycle.
ADVICE — Report the start, not just the job offer. The count turns on employer information with dates inside your OPT period. Report when you actually start, report when you actually stop, and check afterwards that the dates in SEVIS match the dates you worked — a mis-keyed start date manufactures unemployment days out of thin air.
SECTION 06When the Cap Is Reached — and the Grace Period
RULE — Exceeding the cap means you are not maintaining status. The caps are conditions of F-1 status itself, not targets with a penalty fee. A student who accrues more than the permitted days has failed to maintain status, and SEVIS carries a specific termination category for exactly this: exceeding the maximum number of days of unemployment. There is no application that buys the days back.
RULE — The 60-day grace period belongs to the end of OPT, not to the unemployment cap. The familiar 60-day grace period runs after your programme or authorised OPT ends, to prepare for departure or a change of plan; it is not an extension of the unemployment allowance, and unemployment days do not stop accruing because a grace period exists. Our guide to end-of-status grace periods covers how the grace periods differ by situation — read it before assuming any particular 60 days are available to you, because a termination for a status violation is treated differently from a clean completion of OPT.
RULE — Cap-gap does not pause the count. If you move from OPT into a cap-gap extension on the way to H-1B status, unemployment during cap-gap still counts against the same maximums. That interaction belongs to the cap-gap mechanism and is covered in our cap-gap guide, linked below — the short version is that the counter does not stop existing because a petition is pending.
SECTION 07Staying Clear of the Limit
ADVICE — Keep your own ledger. Do not rely on memory or on the portal alone. Keep a simple record of every employment start and end date, every report you made to your DSO and when, and your running unemployment total. If your ledger and the SEVIS counter disagree, the ledger is your evidence for getting the record corrected.
ADVICE — Talk to your DSO early, not at day 89. DSOs can see accrued-unemployment alert lists and can correct employer information that was entered wrongly. If you are approaching the cap, or a past employer was never entered, raise it while there is still time to fix the record — corrections after a termination are a much harder conversation.
ADVICE — Treat qualifying volunteer work as a real bridge, with paperwork. On post-completion OPT, a related, lawful volunteer or unpaid internship role of at least 20 hours a week stops the clock (Section 03) — but only if your DSO has it in your record with correct dates. Get the employer's confirmation of hours and duties in writing before you start, and report it like any other job.
FAQFrequently Asked Questions
Does the STEM OPT extension give me a fresh 150 days of unemployment?
No. The 150 days are the ceiling for your total OPT period, post-completion and STEM combined. The extension adds 60 days to the 90 you had — days already used on post-completion OPT come off the 150, as USCIS's STEM OPT unemployment table shows.
I have a job but never reported it. Am I still accruing unemployment days?
In SEVIS, yes. The counter is built from employer information in your record: each day without employer information counts as unemployment, whatever the reality. Report the employment to your DSO at once and ask them to confirm the dates entered — correcting the record is what stops the fictional days.
Can volunteering stop the clock?
On post-completion OPT, yes — if the role is related to your programme, runs at least 20 hours a week and does not violate any labour law, per USCIS's Policy Manual. On STEM OPT, no: volunteer and unpaid arrangements do not qualify, because STEM OPT requires a bona fide, paid employer-employee training relationship.
What happens on the day I pass 90 days of unemployment?
You are no longer maintaining F-1 status — the cap is a condition of the status itself. SEVIS has a termination category for students who exceed the maximum unemployment days, and there is no mechanism to purchase or appeal extra days inside OPT. Speak to your DSO immediately about your position and options; do not assume a grace period repairs an exceeded cap.
How can I see my own unemployment count?
DHS's unemployment counter shows days allowed, accrued and remaining against your Actual OPT Start Date, and your DSO can see the same figures in SEVIS — including through the accrued-unemployment alert lists SEVP provides to schools. If you cannot see the counter, ask your DSO for your current count and reconcile it against your own employment dates.
