My question involves an arrest warrant from the State of: New Jersey

I have recently been told that there where two sherrifs at my previous address in New jersey where I lived looking for me for not paying my hospital bills. I am currently living in south america and am planning on visiting in two months back into the US.

1. I would like to know if I will be arrested at U.S. customs? or what are my chances for being arrested for this type of warrant ?

2. If yes, I would like to also know if I fly into New york, could this warrant affect me eventhough its from New Jersey ?

I have a clean record until this!
