I received a US visa in the past. I had to fill in an online form, make an appointment which arbitrarily setup for me, visit the US embassy go through security etc, wait in the line for an hour, go through an interview, pay, and then wait for a 1-2 weeks. On the bright side they gave me 10 years visitor VISA so I visit whenever over that period without having to get a new one.
