what do you think the court will decide? community service, fine,probation or jail time?
We cant predict that. Most likely you're looking at a fine, restitution and probation. More detail than that? Can't do it.

then what do you think the immigration services will do? deny the citizenship, delay it by putting me in probation or deport? can I still renew my green card when the time comes if they deny the citizenship?
can I drop my citizenship application now and wait for several years (more than five) since they usually go back and ask only for the last few years?
