<p>Oh, look! Johns Hopkins Admissions has a web site:[Johns</a> Hopkins University Office of Undergraduate Admissions: Apply, FAQs, Early Decision](<a href=“http://apply.jhu.edu/apply/faq/earlydecision/]Johns”>http://apply.jhu.edu/apply/faq/earlydecision/).</p>
<p>Seems pretty clear to me, the prohibition is against applying Early Decision to any other university, and the commitment is to enroll at JHU if admitted under Early Decision. You may apply to any other universities you choose under Early Action or Regular Decision rules, and you may apply to foreign universities. (True, you may not apply to Restricted Early Action or Single Choice Early Action colleges if you’re applying ED to JHU, but that’s not because of JHU’s rules. That’s because the ED application at JHU would violate the REA or SCEA college’s Early Action Rules.) </p>
<p>But Hopkins’ ED agreement is an agreement to enroll if admitted. Yes, there’s the well-known out if Hopkins’ financial aid offer doesn’t make the university affordable. I don’t see any loophole about ditching the Early Decision agreement because you’re going to a university in the UK.</p>
