What you should do is keep handling this yourself and losing or retain a lawyer

How long can a court continue a case?

Continuances almost always benefit the defendant. If he is convicted how is that going to help his job situation?

Can the state of Illinois suspend my drivers license because I received a speeding ticket in Iowa while my license was expired ?

Yes they can. 6-206 a 19 19. Has committed a violation of paragraph (a) or (b) of Section 6-101 relating to driving without a driver's license;

Can I have a suspension of my license ceased in Illinois.

Iowa reports a no valid license conviction to Illinois, they will suspend. You need to get the Iowa conviction fixed.

There don't have to be workers present. And the state can amend the ticket to allege your speed.

Will I be charged? What will be my consequences and how may I mitigate it? (Illinois)

Springfield (if it's a city ticket( and Sangamon County (for a state charge) both have diversion programs if you know how to ask.

In a case such as this one, my guess is that if you request a PD, the state will agree not to seek jail time and then he is not entitled to a PD.

I had a DUI and driving on suspended license in 2013 and just received a driving on revoked license is it a felony

If the first driving suspended was a) a conviction and b) due to a statutory summary suspension, Champaign Coubty will likely file felony charges.

A lawyer may be able to get the conviction vacated and supervision. it's not like this should have surprised you. They sent you a warning letter...

I went to my court date which i believe was my last, the judge said my case is terminated. Does that mean i am done w/ court?

Finished with court as long as you don't' get in trouble again.
