My question involves criminal law for the state of: I'm looking for a little help on what I should do with my situation because I've never been arrested and don't know much about the law in USA. On saturday my son (18 months old) was so cranky so i decided to take him for ride and my friend came with me to by cigaret. Since he forgot his wallet he asked me to go and get cigaret(Basically i dont have the habit of drinking and smoking).
While walking towards the shop one guy approached me and told "he is under 19 year old" Can u help me to buy a can of beer. At that time i couldn't realise anything and i dont know about the age limits for drinking in USA and my complete focus was at my son who was crying in car with my friend. So i bought the can of beer immediately a bunch of cops showed up and arrested(hand cuff) & charged me for furnishing alcohol to a minor and the cited code "Business & Profession Code 25658(a)". Basically that was a sting operation done by the cop.
1.What will be the punishment for this? (I'm an Allien worker in USA )
2.Does this affect or deny my H1B visa?
3.Does this affect/deny my green card process? I'm waiting for priority date to apply for I-485?
I have my Perm and I 140 approved and waiting for priority date so can i still apply for I 485? will i still able to get my green card?
4.Do i need to see Attorney (which kind)? How much money required?
I am having sleepless nights and in really bad condition.Blaming myself for this.Please help me .Please guide me what to do.
