I am a US citizen and lived in Middle East for a couple of years where I got a Credit Card from a bank there. After a year or so of using and paying my card on time, I found out that there are charges that I did not make. I stopped paying and my assignment was completed so I returned to US. Does the credit card company or the bank that issued the card has any jurisdiction to come after me legally here in US? They never investigated the fraud and only wanted me to pay it which I refused.
