WJ college financial aid

<p>Hello everybody</p>

<p>I'm an international student. There's something I couldn't understand and you might help me in it.
In the website of Willam Jewell college it's said that the college cannot send an I-20 to an admitted student until it is determined that the student will have the financial support required to cover the costs of attendance.
So I'm supposed to have enough money to pay for the attendance, then why I'm going to apply for financial aid ?
It's because I can't afford it that I'm going to apply for aid.
I'm sure there's an explanation otherwise this doesn't make any sense</p>

<p>Thanks in advance!</p>
