I knew about this thing in other post, however i am mentioning the same subject, but from a different angle.
I heard about the new security procedures of running a background check for passengers traveling, and i tried searching for the official announcement of it, but i couldn't, so i thought maybe i post my questions here, perhaps someone can help
1- If some body have an official link for this website, or any link please send it to me or post it
2- if some one can explain to me about this new procedure in terms of
a. How is this search done
b. is it done when you purchace your ticket or when the day of travel.
c. why are they looking at the financial information
d. what if you were a non us citizen visiting the USA and traveling domestically?
any help is appreciated
