"NO File" disposition on domestic battery misdemeanor - Waiting period on filing for Naturalization?

[suzannenpb]

Question: How long after "No File" on domestic battery "Misdemeanor" case can greencard holder file for N-400 Naturalization?

BACKGROUND:
I was arrested for domestic battery (misdemeanor) Florida Statute # 784.03(1) based on an anonymous call. My spouse filed a legal affidavit with court the next day stating that things were blown out of proportion with misconstrued facts in the police report. Florida State gave "No File" final case disposition i.e. no charges, no fines, no conditional settlement, no probation.

DETAILS -
Greencard application through marriage to US citizen.
| Jan 2011 - Received Conditional Greencard
| May 2013 - Received Permanent Greencard (IR6)
| Aug 2013 - Arrested for domestic battery misdemeanor, Florida Statute # 784.03(1). Final case disposition with "No File" i.e. no charges, no fines, no conditional settlement, no probation.
NOTE: I have a certified copy of the "No File" final case disposition from the court.
| Oct 2013 - Eligible for early filing of N-400 naturalization.

Should I apply for naturalization now or wait? If I wait, then how many months is advisable? 5 years or 3 years (since my application right from the beginning has been marriage based)?

I plan to hire an immigration attorney but I am asking the questions above because I wish to know if I should hire one soon or wait for 3 or 5 years and then hire one. Is there a probability of successful naturalization if I hire an attorney now or irrespective of attorney or not, I should wait?
