<p>Wash U isn't even need-blind to domestic students, much less international students. I'm pretty sure Connecticut College isn't need-blind either, considering its small endowment. Need-blind for internationals means international applicants who can pay will be as disadvantaged as international applicants who can't pay. Given that the OP can pay, applying to non-need-blind schools would be advantageous.</p>
<p>Since the OP is interested in engineering, I recommend Olin College. She'll be a domestic applicant for Olin since she doesn't need an I-20 or financial aid beyond the Olin Scholarship.</p>
