> Need-blind admission requires need-based aid.

What are you talking about here?

Need-blind admission would be "we'll make the decision of whether to admit you without considering whether you can afford to come". It's analogous to an iPhone offered for sale at $1000, even if you can't afford to pay $1000 for an iPhone.

Need-based aid means charging less money to people who, in your judgment, can't afford more. It's analogous to finding scruffy people on the street and giving them 70% off coupons for iPhones.

There is no logical dependence from one to the other. An Apple store does practice need-blind admission, and definitely does not practice the "required" need-based aid.

Not exactly the same concept. Need-based admission requires need-blind aid, but not the other way around: especially for foreign students, many good US colleges need-based aid if you get an offer, but are less likely to admit you.
