Back in June we ran an issue telling you to treat full-time CPT as a limited resource, keep a running tally, and do the math before you sign. That advice was half right, and the wrong half is the half that costs you paid experience.

Here is the correction. Full-time CPT is not a meter that ticks down. It is a cliff. The University of Chicago's international office states it in one line: twelve months or more of full-time CPT makes you ineligible for OPT, and part-time CPT has no impact at all. Brown says the same thing. So does Ohio State, which adds the detail that makes it concrete: any amount of full-time CPT adding up to less than twelve months has no impact on OPT eligibility whatsoever.

Auburn puts the arithmetic in the bluntest terms I have found. Fifty-one weeks of full-time CPT and your OPT is completely intact. Fifty-two weeks and it is gone. There is no partial credit, no reduction, no sliding scale. Winona State tells students they can use eleven months and twenty-nine days.

So every student who turned down a spring co-op to "save CPT" while sitting at four months of lifetime usage gave up real paid work to protect something they were nowhere near spending. Meanwhile the authorization that genuinely does run out, OPT, is getting drained by a mechanism almost nobody tracks. Spring and summer decisions are being made in the next six weeks. Here is the arithmetic that should drive them.

Find your actual number before you decline anything

Most students carrying this anxiety have never seen their own total. They have a vague sense of having "used some CPT" and they make decisions off the vague sense.

Your DSO can pull the exact figure out of SEVIS in about four minutes, because every CPT authorization you have ever had is recorded there with a start date, an end date, and a full-time or part-time flag. Ask for it as a number of days, not a feeling.

Then do the subtraction. If you are at 120 days of full-time CPT and you are weighing a twelve-week summer internship, that lands you around 204. The cliff is at 365. You are not close. Take the role, and stop paying a real cost to protect a theoretical one.

The clock counts authorization, not the days you worked

This is where the cliff can sneak up on someone who genuinely is near it, and it is the detail that converts the rule from trivia into something you act on.

Ohio State's international office spells it out: USCIS counts days of CPT authorization, and at 365 or more days of full-time authorization you are ineligible. Not days worked. Days authorized. If your I-20 says May 11 through August 29 and you wrapped up two weeks early, you still spent the full authorized block.

So ask your DSO to authorize the dates you will actually work, not a padded window with buffer on both ends. A two-week cushion on each side of three summers is two months of cliff you burned on nothing. One more trap worth knowing, flagged by several international offices: overlapping part-time CPT authorizations can be counted as full-time days. Two twenty-hour roles running at the same time is not two part-time authorizations in the system's eyes.

Part-time CPT is the genuinely unlimited one

Here is the move that follows directly from the rule, and it is the single highest-value thing in this issue.

Part-time CPT, defined as twenty hours per week or fewer, does not count toward the twelve-month threshold at all. Not at a reduced rate. Not partially. At all, no matter how many semesters of it you do. You could work part-time on CPT every term of a four-year degree and walk into graduation with your full twelve months of OPT untouched.

That reshapes how you should build a schedule. Term-time roles at twenty hours or fewer are effectively unpriced. Concentrate full-time CPT in summers, where the hours are worth more to you anyway, and keep the academic-year work part-time. If a term role is offered at twenty-five hours, ask whether it can be structured at twenty. That five-hour difference is the entire difference between spending cliff days and spending none.

OPT is the budget, and it is the thing actually draining

Now flip to the authorization students almost never guard, because this is the inversion that matters.

OPT is twelve months per education level, and unlike CPT it works exactly like a budget. UChicago's page is explicit: all previous periods of OPT at the same level are deducted from the twelve-month total, and part-time pre-completion OPT is counted at a half rate. Their example is four months of part-time OPT subtracted as two.

So pre-completion OPT, which some students use for an internship when CPT is not available, comes directly out of the post-graduation runway that is your actual bridge to a full-time job. One useful exception: on-campus employment does not count against the twelve months at all.

The correct mental model is the reverse of the one most students carry. Treat CPT as abundant until you are genuinely approaching a year of full-time authorization. Treat OPT as scarce from day one.

The cliff resets when the degree level does

Last piece of arithmetic, and it changes the stakes for anyone with graduate school in the plan.

Both clocks run per education level. Twelve months of full-time CPT during a bachelor's degree has no effect on OPT eligibility at the master's level, where you get a fresh twelve months. If you already know you are heading to a graduate program, the undergraduate math carries less weight than your anxiety suggests.

The reverse also holds, and it catches people. If you use OPT at a higher level and then enroll in a lower one, you do not get a fresh allotment going backward.
