Is Early Decision also binding for universities outside US?

<p>Thank you!, but I was bit confused from this post few years ago,
<a href=“http://talk.collegeconfidential.com/columbia-university/1067213-decision-help-oxford-columbia-2.html[/url]”>http://talk.collegeconfidential.com/columbia-university/1067213-decision-help-oxford-columbia-2.html&lt;/a&gt;&lt;/p&gt;

<p>and post #23 says “The OP is perfectly within his/her rights to decline an ED offer in favour of Oxford (or any foreign university). There’s nothing Columbia can do about it, and Oxford won’t care.” So I was wondering about the truth…</p>
