Weekend feature: American homeland security | Special reports | Guardian Unlimited
Rather shocking article I found off digg.com. A British writer flew to Los Angeles to perform a freelance assignment for The Guardian (newspaper), but did not have a "journalist's visa." Evidently this is a lesser-known requirement for foreigners travelling to the USA--if you're coming here to do any form of journalism, you need to apply for a journalist's visa, the typical 90-day "visa waiver program" does not apply.
The story left me rather disgusted with the state of our border security, not that it's the first time I'd heard about it.
PS- The article is a bit old, written in 2004. Hopefully things have shaped up since then? (Yeah right)
