They didn&#x27;t answer the question, but I&#x27;d guess it&#x27;s because it rests on their relationship with &quot;partner&quot; organisations. If those companies largely reside in the US, and if most students can&#x27;t be expected to get a working visa in the US, then Udacity could find themselves paying for a lot of students&#x27; courses themselves, rather than having some &quot;employer of last resort.&quot;
