I've honestly been dreading/avoiding getting a visa to visit the USA because of all the red tape, bullshit and silly payments that need to be made for them to say "no" to your application and for you to do it all again.
Seriously, fuck traveling to the USA if the won't let us do it legally. It's actually cheaper, easier and more efficient (and welcoming) to go through the Southern border than through a TSA checkpoint at an international airport.
Americans need to realise this and change it or see less and less people travelling legally to the USA
