<p>Because it is very expensive. I’m an international student and I was spending about $60k/year on tuition + board every year. (I did a dual degree)</p>
<p>Also, you can forget about financial aid in the US of you’re an international student. It is never offered for undergrads(At least I have never seen it). In fact, you have to prove that you can pay before they officially admit you and send you your I-20.</p>
<p>Your best bet is to apply for an international scholarship in your home country.</p>
