Hi!I'm on thinking to go to USA with holiday visa,because i have a job offer from a friend,while waiting for a decision for my 121.I want to ask you when a case officer contacts you,he/she contacts only through e-mail or both by phone and e-mail?I have provided a valid e-mail but i'm afraid if they contact me by phone and they don't find me.Do anyone know something about this matter?Thanks in advance.
