<p>I would be willing to bet that that most colleges allow students who have completed less than a year (typically 24-30 credits) to apply as freshman. Here are some</p>
<p>Harvard (one continuous academic year to be a transfer)
Columbia (you must have more than 24 credits to be considered a transfer student)
Dartmouth (anything less than one full year of university coursework, you would apply as a freshman)
Swarthmore (admissions status for less than two semester is determined case-by-case)
Amherst (at least one year as a full-time student elsewhere)
Wellesley (only eligible for transfer admissions with at least one full year of coursework)
Emory
Vanderbilt (after one semester)
Washington & Lee
Duke
Wisconsin-Madison (must have at least 24 semester hours)</p>
<p>In fact, it would probably be more prudent to list the exceptions to this rule. Stanford is a notable exception - any student who has enrolled either full-time or as a degree-seeking student after graduating from high school must apply as a transfer student. Caltech is a bit ambiguous - they just say that transfer admissions will be considered for those who “have enrolled at a college and earned credit for courses,” which could indicate that anyone who completes at least a semester is a transfer but a person who doesn’t earn any credit may not be. Case Western seems to imply that those with one semester of college credit may still be considered transfers.</p>
