Without a doubt, the two biggest concerns for people on the registry seem to be finding a place to live and finding a job.
Looking for a job is stressful for anyone. Any ever convicted of a felony fears that inevitable question on the application, "Have you even been convicted of a felony?" For the registered sex offender, it's even worse, trying to figure out what to say to the next question, "If yes, please explain." Fortunately, this won't be a problem anymore starting in January, 2015. Illinois passed a law that bans the conviction question on applications.
This doesn't mean that your potential employer can never ask you about your criminal history. If you get selected for an interview, or if you get offered a position, then they can ask. But the fact that they can no longer put it on the initial application means you have better chance of getting an interview!
So what should you do if you are asked about criminal history in an interview? Should you lie? Should you be honest up front? Should you just go looking for someplace that DOESN'T ask that question?
Obviously, everyone's situation is different. People have different skills, different likes and dislikes, different personalities, and different offenses. There is no ONE RIGHT ANSWER for where to apply or what to say on applications or in interviews. Below are some links to general guidelines that may help you in your job search.
One thing is certain, though. There ARE people or places out there who are willing to hire you despite your background. Just remember, they say you will get at least 4 "no's" before you get a "yes." For the registered sex offender, it may be many more "no's" but the "yes" is out there if you keep trying.
