I posted the same question yesterday on AVVO, an attorney responded this

"Even though you thought nothing would come up, the question is clear:

Part 4, Question 1. Have you "EVER" been arrested for, charged with, OR convicted of a felony or misdemeanor.

If you did not disclose the arrest, there is a big probability of having your application denied."

I sent in the disposition already, it was received 7/9
