My question involves criminal records for the state of: Illinois

Hi,

My question:
1. I had a Driver's License Issued by Arizona.
2. Got a speeding ticket in Indiana, while driving at 70mph on 55 mph.
3. Arrested in Schaumberg, IL at a traffic stop.
4. I lost the Ticket and could not pay the speeding ticket, later I moved to IL. I had no idea that my Drivers License was suspended.
5. Got bailed off the same night of the Arrest. Got a Court Date, Paid the Court fine, Paid the Speeding Ticket Fine in Indiana.
Acquired IL Driving License.

I want to know what is offense called. Is it a misdemeanor, infraction, or conviction. Can any body explain these three regarding to my case, as i don't
understand the real meaning of the terms actually.

** If there is a background check for on my name does this Arrest comes up on the Home Land Security system? If so Can i get it Expunged or Sealed.
And what is the process.

Thank you all.
