<p>Here are the rules that I had posted in a different forum</p>
<p>OK, here are the rules:</p>
<p>Early Decision (ED): If you apply to a school with ED, you cannot apply to any other school with Early Decision. You can however apply to a school with early action (EA) expect if that school with early action has restrictions i.e. Yale and Stanford. If you get admitted to a ED school, you are bound to join the ED school (there are few exceptions for financial reasons, but if you are not sure you should not be applying ED anyway.) The obvious reason why you cannot apply to 2 ED schools is that if you get accepted by both, you are expected to attend both, which is not possible.</p>
<p>Some schools Like Carnegie Mellon, Harvey Mudd etc. have two Early Decisions ED I and ED II, with different deadlines. So you could apply to say Dartmouth which has ED (just one) and if you get rejected, you could be apply for ED II at CMU, as the deadline for ED II is after the results come from Dartmouth. Most schools with ED just have one deadline.</p>
<p>Early Action (EA) is non binding, you do not have to accept the offer. So you can apply to one ED school and several EA schools without a problem, unless the EA schools are Yale and Stanford. Yale has Single Choice Early Action and Stanford has Restricted Early Action. Some of the top non restrictive EA schools are Caltech, MIT and Chicago where you can apply to all three of them EA without a problem.</p>
<p>Yale and Stanford expect to you to apply to only them EA ( you cannot apply to any other school either ED or EA).</p>
<p>Here are the rules for Stanford's REA. Yale's should be similar.</p>
<p>Facts About Stanford’s Restrictive Early Action Program</p>
<p>** Stanford’s Restrictive Early Action program is a program for students who know, at the time of application, that Stanford is their first choice – and not a program that should be used as a strategy for admission. This is the design of a Restrictive Early Action program versus a more open Early Action admission program offered at other institutions.
* Because a student's financial aid offer is often a critical factor in making a final college choice, Stanford's Restrictive Early Action program provides time for families to consider financial aid awards from multiple schools before making a final commitment to enroll.
* Applicants agree not to apply to any other school under an Early Action, Restrictive Early Action, Early Decision, or Early Notification program.
* Applicants are allowed to apply for Regular Decision admission at any number of other colleges and universities.*</p>
