We went in bus and came through laredo. I was so scared I thought I was going to be sick . There are agents waiting for you when you get off the bus and they ask to see your documentation. I showed them the AP form along with the approval letter from Deferred action and my passport but noone was interested in my passport just teh letter that needed to be stamped. They told me to be sure and get it stamped. Had to go to another line were they check your documents again and he actually called someone over to ask about the form, once the other guy got there he told him to just admit me and he escorted me over to a small office and hand the papers to another agent who told me to have a seat. It about 15 minutes before they callled me in. Once they took me in he took my finger prints and was asking me where I live and if I worked, it didn't feel like I was being interrogated more like a conversation. After a few minutes I saw my picture pop up on the screen with some info. He said OK you can go outside while I get this stamped. I went outside and he came out after about 10 minutes, handed me the AP paper along with a small form I-94 and he said this was my ID while in the US and that if I was questioned to show that as my ID
