i went to prison(2004) ,got out(2007), finished my parole(2008).when i finished parole i was not told to sign up for probation by the officer.

Although this question appears in the Iowa topic list, the question may be more properly answered by an attorney from the State of Georgia.  I am assuming that the defendant was convicted in Georgia, served time in Georgia, and now has a warrant from Georgia.  The question writer needs to contact a Georgia attorney to resolve the issue.  If a warrant has been issued, then the person is subject to arrest at any time in Iowa, and if Georgia refuses to extradite, then the legal issue will not be resolved, with the person continuing to be arrested in Iowa and eventually released after Georgia refuses to pick up the person.  If Georgia does extradite, then the person will be returned to face Georgian justice.  Either way, a Georgian attorney would be the appropriate assistance to resolve the issue. Often probation issues can be resolved by a local attorney.
