The VISA Central company is a complete ripoff in so many ways, in my opinion. Just for grins, I asked them how much they charge for obtaining an Australian ETA, the electronic visa. This is something you can just go online and get yourself for $20 AUD, about $18 US, in five minutes or less. They charge $45 total!!! And it would not save you any time, it would take longer going through them.
According to their website: "VisaCentral simplifies the application process by eliminating the need for you to visit, communicate, and correspond directly with the DIAC."
None of which you have to do, all you have to do is obtain it online directly from the Australian government web site.
What a complete crock. Anyone who uses this company deserves to be parted from his/her money. I wonder how much Delta gets as part of this business relationship.
