I applied for an ESTA application for my Japanese wife to visit Guam. I applied through their official government website. The fee is $14USD for the application. Once my wife's application was confirmed, there was a bank fee of $104USD directly from my account (that was only listed on their official website). A 3rd party called "eVisaprocessing" charges $90 for an application that costs $14. Total scam that cannot be traced. ESTA site repeatedly posts about not using 3rd parties (I used their official government website) and to watch out for scam sites. They also make it very apparent that NO REFUNDS will be given regardless of a successful or failed application. They KNOW about this problem! They either have a hacked payment service that allows "eVisaprocessing" to grossly overcharge customers or they have a deal with them. They deny all accountability throughout their site and know that this is a huge problem.
