My question involves criminal law for the state of: Virginia
I was caught by LP for changing a price tag on a luggage and buying the item. The price of the item was $80 and i placed a tag for $34 on it and purchased the item and was about to leave the store and LP told me to come in the back. Police were called and I was charged with petty larceny and have to appear in court twice. First i have to appear on Monday June 9th and then July 14th. The store has video tape of me which the police looked at before charging me.
This is my first offense of any kind and i was very foolish to do anything like this.
I need to know
Should I hire a lawyer even though I plan to plead guilty since they have the video tape?
What i should do on Monday in court?
How this will affect my immigration status? (Legal Resident at the Moment)
What could be the possible outcome of the case with above info in mind?
Any help is appreciated.
