If you are from US I want to let you know about a scam. Here in asian countries people with good enlgish accents are recruited to pretend to be US citizens and claim benifits that are unused by the real people. There is a whole proper process of how this works. The recruit is given full identity information and a software to make the call appear from the US. The officials on the US side are in on this and get a share for each successfull claim.
