How will the school defer my enrollment?

<p>I apply to defer my admission to fall semester 2012 because of some necessary reasons,however, the admission officer told my he was updating my application request to fall semester 2012 and added my extra materials to my file. Dose it mean I need to pass the readmission if I want to get my new offer? It worried me a lot... will the decision change? do I need to apply another school? = = many thanks</p>
