Are you on deferred? If you just got a citation and must appear in court, that does not mean you are on deferred but that you are facing the charge which carries from probation up to 6 months in jail and a fine up to $2,000.
What you need is a pretrial diversion if you can get one. A pretrial diversion will help you avoid a conviction and have the ability in the future to expunge your record.
You need to hire a lawyer to represent you.
Not only do you need a knowledgeable criminal defense attorney, but you need an attorney that understands the immigration consequences. A theft charge is a "crime of moral turpitude," so this can have a serious impact on removal or admissibility. For most immigration purposes, a "deferred adjudication" is treated the same as a conviction. You need: 1. A good criminal defense lawyer; 2. A lawyer that knows the immigration consequences; and 3. A lawyer familiar with all of the possible dispositions in your jurisdiction (presumably Travis County). Good luck.
If it is your first offense, you should hopefully be able to get a deferred prosecution on the charge or a reduction to a Class C with a deferral - either will ultimately dismiss the charge so you can expunge it. You can also have your attorney look into a pretrial diversion application should will get it dismissed under the same circumstances.
I assume you are not already on a probation of some type?
