According to the TSA, you can travel within the USA with a foreign passport.
I was wondering if anyone has flew within the US with a passport (from Central, South America, Mexico, etc.) that does not have any stamps on it???
My friend and I want to go travel within the United States and the only primary form of ID we have is Salvadoran gov't issued passport (no stamps, etc).
Please let me know if you or anyone has done this and if the TSA checks for a stamp even??
