N400 with Domestic Violence, Need help

[n400_j]

I had my citizenship interview couple of weeks back at Charlotte North
Carolina. Officer didn't make any decision. I am little bit worried
about deportation.

I was charged with Assault on Female and Communication Threats in Dec
2002 (North Carolina). Detained for 48 hours and released on secure bond. It was with my wife.

I received 12 months supervised probation under the differed prosecution and voluntary dismissals. I signed this form

http://www.nccourts.org/Forms/Documents/156.pdf

Court also asked me to join change program for 6 months (June 2003). I
completed change program in Dec 2003. After completing change program
Case was volunteer dismissal in Dec 2003 so is probation (after 6
months)

I applied for Citizenship based on 5 year GC but charged were filled 3
years back.

I read quite a few article on the web and book "Immigration
Consequences of Criminal Activity" by Mary E. Kramer. There is a
section in chapter 2 "Pretrial Intervention or Diversion" procedure
does not result in a conviction for Immigration.

I would like to understand and find out if singing above "differed
prosecution and voluntary dismissals" form consider as "Pretrial
Intervention or Diversion" or is it considered as "plea guilty". I
don't see any specific language in terms of "plea" in the form.

Will INS put me in deportation proceeding? If yes then Does it make
sense to withdrawal application after the Interview to avoid any
deportation proceeding.

Any reply or advice will be appreciated.
