I recently just experienced a similar situation. I was offered a position into a prospective PhD program, and was told the final decision from the graduate school would come shortly after. I was worried because my undergraduate GPA is lower than what the graduate school required, but sure enough I received a decision letter a few days later confirming that I was indeed accepted for admission! 

I think you only apply if you are in financial need. Deferring current student loans only requires proof you are currently enrolled. 

University of Oklahoma, sorry
