When I successfully (legally) immigrate into the USA, I had to move some of my computers which contain a client's sensitive data/project.
I was surprised when I found an article that says the CBP have the right to scan a computer (and can force me to enter the truecrypt password!)
I am unable to wipe any data, but leaking extremely sensitive data is a big problem for me (What should I say to the client, "the government wants your project"?)
I swear that I am not a terrorist of course, but I want to know what other businessmen do in this kind of situation.
