What can happen ifI have outstanding warrants for my arrest?

You didn't give much by way of details.  However, one thing is for sure, do not ignore this situation. If you are stopped for something even as minor as jaywalking you will be taken into custody (and probably extradited back to IA on the felony warrant).  Additionally, this will all turn up on an employment background check and on a security check with respect to obtaining a passport.  This is true no matter what state that you are now living in.  You will need to appear in court in both states.  The fact is that you are in serious trouble and need to seek legal counsel ASAP.  A skilled criminal defense attorney will best be able to represent your rights. Since you will be facing charges in both states, you will need to hire attorneys in each one.

If money is an issue, see if you qualify under the income guidelines for the Public Defender or Legal Aid.  If not see if they can recommend an attorney that may take the case "pro bono" (that is for free); many will volunteer their time for cases such as this.  Also, if there is a law school nearby to the court where the warrants were issued and check to see if they run a free/low cost clinic; typically they do. Also, contact the local Bar Association in the applicable county; they may have a list of attorneys who will take your case "pro bono" (for free) or at least for a reduced fee based on your income/circumstances.
