Answer 2

You seem to want a lot of detailed information, and you have asked the question twice.  Looking at the other questions you've asked about getting your friend into the U.S. when it sounds like she's a bad visa case, I must admit I'm a little worried about what you'd do with the information if I gave it to you.

Answer 3

You sure you're a citizen? If you really are one then rest assured the methods are 99% foolproof. You don't need to know the methods because it might open up doors for people who want to create fake visas for others who are willing to pay for it.  

For your own safety, Just trust Uncle Sam. ^_^

Answer 4

Each visa has a barcode and come with  packet. Once you arrive in US immigration.. they're checking  packet, scanning visa and  re-fingerprints again.  

How do you escape from this?
