Living abroad I'm a bit paranoid when it comes to my financial accounts and credit rating back in the States. It would really suck if I were the victim of fraud and didn't even know it. Even worse would be dealing with identity theft while living overseas. Below I compiled some helpful links and tips for keeping a close eye on your USA credit situation.
NOTE: Many of these sites are only accessible from within the US, so I recommend a service called Getflix that offers VPN connections. This very affordable service allows you to access these sites while abroad.
