Before submitting the Common Application, I checked the box that said I qualify for a fee waiver. And I’ve submitted some of my applications now with this option. I just wonder if there is anything I should do regarding the fee waiver.Is it something I have to wait to hear about from individual colleges or the Common Application? Are there people checking to see if I am qualified for the waiver? Should I be sending in supporting documents, and what if I don’t?
Thanks in advance for any replies 
You have done your part. When your GC logs on to CA, they will approve your fee waiver if you are eligible to receive a fee waiver
