Question for you wise people! (regarding travelling out the USA)

[lamayela]

Hi guys I was wondering what the airline and security check point ask you for when you leave the USA. I have my passport and VISA none of them expired of course and and am in the USA willing to travel to Germany next month, I was wondering what they ask you for, the thing is that I dont have my I-94 of when I entered the USA.

Any help is appreciated.

Thanks so much in advance
