Do what you've been instructed, and keep a record of your contacts with the court. If the charge has not appeared by January, check with the court upon your return. If your ticket has made its way into court during your absence, the court will likely issue a civil assessment fee of $300 for the failure to appear. Ask to have that vacated when you're eventually able to address the issue, assuming it arises.
Sorry to hear about your situation and the annoyance you have to endure!
If you must leave the country and therefore cannot appear in court, you can hire an attorney to make appearances on your behalf.
The responses given are correct. Fortunately, while you are away you can still check online to see if it ever hits the system. I would have an attorney on call in the event something should happen while you are away.
I am somewhat confused with your statement that "you received a ticket on 6/4/10- but did not receive it in the mail". What kind of ticket was this for?
