green card renewal.

I have to renew my green card soon. (10 years as a Permanent Resident) However, by mistake I grabbed an old checkbook of a closed account. (my own checking account) went to the grocery store and paid about 70 dollars for groceries. went home and that's it. about 2 years later I was hired for a job but one day before my starting day, I was told that they couldn't hire me because I had a warrant for arrest and they couldn't hire me. they gave me a case number and I went running to the court to find out. They told me that it was for writing a bad check for $70 at a grocery store. when they showed me the check I was surprise because I didn't even realized I did that and it was totally unintentionally , I was never notified. Well, I realized that since it was from a bank that I didn't deal anymore, there was no way to contact me years later. I said, well what do I do. he said. pay it and some other fees, like a total of $90 dol and it will be dismissed but sometimes it comes up as dismissed
