Depending on the degree of any record check, an outstanding warrant may show up. Out of state warrants may or may not show up. You need to hire an attorney in the state where the warrant was issued ( I know you say you can't afford it) to have the case redocketed and get the warrant recalled/set aside ( or if arrested on the warrant, you will need the money to make bail and hire an attorney or remain in jail until a public defender is appointed if you are indigent).
I am trying to give you a general answer to your question. We do not have an attorney-client relationship by this response on the avvo website. I have not been retained to represent you. I am licensed to practice law in Kentucky and in federal court in this state and the Southern District of Indiana. You need to seek legal advice from an attorney licensed to practice in your area..
