“Early” is not one plan. It is two.

An American application gives you two chances: an early round in the fall, and the regular round at year's end. Most families who sit down with us begin by asking how ED differs from EA — a fair question, and exactly where this piece begins. It assumes nothing and moves one step at a time. The scope is the top 40 or so U.S. research universities, seen from where an international applicant in Vancouver sits.

Regular Decision first. It is simple

Regular Decision is the ordinary year-end application. Most schools close between January 1 and 6 — in practice, the application a family is still writing on New Year's Eve. Nearly every answer is out by the end of March. You may apply to as many schools as you like, and you have until May 1 to pick one offer.

California is the one exception. The UC system has no early round at all. The filing window runs October 1 through November 30, and answers come in March. There is no such thing as “using UCLA as our early.” UC returns once more in the money section.

Early comes in exactly two kinds

Anything filed in the fall is “early.” The acronyms look like a zoo, but there are really just two kinds: you either make a promise when you apply, or you don't.

Early with a promise — ED

The student, a parent, and the school counsellor sign an agreement: admit me and I will enrol. Due in early November, answered in mid-December. An admit means every other application is withdrawn. That promise is what “binding” means.

Early without a promise — EA

You simply apply early and hear early. An admitted student still has until May 1 to decide. MIT and UChicago are the classic examples; WashU added one this year.

The ED promise is heavy, so one rule follows from it: the agreement can go to only one school at a time. Your counsellor has to sign it, and no counsellor signs two.

Four schools put a condition on EA too

Harvard, Yale, Princeton, Stanford. Their early round is promise-free EA, but it carries a condition: apply early to us, and you may not apply early to any other private university in the U.S. That is why it gets a name of its own (REA). Georgetown and Notre Dame run a softer version — other EA applications are fine; only the ED promise is off the table.

That condition is what forces the conclusion. Whether you sign an ED agreement or file at one of the four, the fall holds exactly one play. Sign Duke's ED and Harvard disappears. File at Harvard and Duke's ED disappears.

Ordinary promise-free EA stays out of this arithmetic. MIT and UChicago EA do not block each other, or anything else. One catch: in a year when your play goes to one of the four, those EAs are off the table too — they are U.S. private universities.

The exception that only matters from Vancouver

The early admissions program is at an institution outside the United States. — Yale, an exception in the Single-Choice Early Action policy

The four schools' “nowhere else” clause comes with a list of exceptions, and the line above is on it. Universities outside the United States are not blocked. Harvard and Stanford print the same exception. So a pending Harvard file sits comfortably beside applications to UBC, Toronto, and McGill — no rule is broken. The U.K.'s October 15 UCAS deadline, for Oxbridge and for medicine, stays open as well.

Turned down in December? January offers one more

A denied or deferred November card is not the end. A group of schools accepts the same signed promise again in early January — the round is called ED II. Rice, WashU, Johns Hopkins, Emory, UChicago, NYU, and Vanderbilt all run one, answering between late January and mid-February. Stanford's own policy says a student it turned down may go to another school's ED II. But Duke, Northwestern, and the entire Ivy League offer no ED II. Walk past those doors in November and they do not reopen that year.

UChicago has one extra door

Here is the heart of this piece. UChicago runs one door that opens before everyone else's. It is called ED Zero — officially the Summer Student Early Notification, or SSEN. Applications run September 1 to October 15, and the answer comes before November 1: the earliest admission answer among top U.S. universities. It carries the same promise as ED. And it has one condition: a UChicago summer program completed during high school. The online course ($4,980) counts, and any high-school summer counts. UChicago's official application page says “a choice of four application plans.” This fifth door is not on the application page. It is on the summer-program site.

The real value of this door is not the early answer. It is that the answer lands before other schools' ED deadlines. An ED promise takes effect only upon admission. Denied or deferred, it is as if nothing happened — and the November 1 card is still in hand. The play most students get to make once each fall, this student makes twice. Count January's ED II and it is three. Two footnotes. The promises run in sequence, never two at once. And an October 15 filing may not hear back until the last days of October, so the second application has to be finished before the answer arrives.

September 1

UChicago ED Zero opens

October 15

ED Zero closes

Before November 1

The answer. An admit sets off the enrolment promise, and the season ends there

November 1

Other schools' ED deadline. Denied or deferred, this day's card is still in hand

Early January

If that fails too, ED II remains. The fall play can run up to three rounds

An early deadline is not an early answer

A few public flagships close as early as October 15. Then look at the answer dates. UT Austin replies by January 15, and UNC answers anyone outside North Carolina by February 15. The deadline is early; the answer arrives on a Regular Decision clock. Georgia Tech's October 15 window is for Georgia students only — an international applicant files by November 2 and hears in late January.

A pattern emerges. Nearly every door that answers fast — in December — wants the promise: Florida's ED on December 11, private ED in mid-December, the ED Michigan added just last cycle by late December. A fast answer costs freedom. The exceptions are the three promise-free EAs: MIT, UChicago, and WashU answer in December and bind nothing.

The money

At most U.S. universities, an international student's aid application becomes part of the admission decision. Stack ED on top and the risk doubles: admitted means enrolled, so there is no comparing what other schools would have offered. A family that needs aid has to be that much more careful about where the promise card goes.

Within the forty schools this piece covers, seven review international applicants without looking at the aid application and then meet full demonstrated need:

• Harvard — “regardless of nationality or citizenship”
• Yale — “regardless of citizenship or immigration status”
• Princeton — full demonstrated need met for every admitted international student
• MIT — “need blind and meets full need for all students, foreign and domestic”
• Dartmouth — from the Class of 2026 (students who entered in fall 2022)
• Brown — from the Class of 2029 (entered fall 2025) — every current applicant is covered
• Notre Dame — since September 2024

Five of the seven — Harvard, Yale, Princeton, Notre Dame, and MIT — offer a promise-free early door: apply unbound, and the aid application costs nothing in the review. At Dartmouth and Brown, the only early door is ED. The other end of the spectrum is UC: no need-based aid for international students at all.

UChicago ED Zero opens (summer-program alumni only)

October 1

UC filing opens

October 15

So the question was never “should we apply early.” It is “which door gets the one card we can play at a time.”

The answer is different for every family. It depends on the school list, the finances, and how much of the application is genuinely ready by October. For some families the card belongs in November; for some, the January card is the real play; for some, the card should not be played at all. That per-family read is the work we do.
