i decided on my case study for one of my art classes it will be this

http://www.sexworkerfest.com

it looked pretty cool, check it out

the organizer of this festival is also in charge of bayswan at http://www.bayswan.org

they are san fancisco based, there seems to be lots of interesting things in that neck of the woods

this is an interesting site from LA

http://www.iswface.org

and look up http://www.nswp.org, and both san fran and LA have COYOTE chapters

on the nswp (Network of Sex Work Projects) site, have a look at the Mobility section on the sidebar (no actually i just got it by scrolling to the bottom of the front page...) it may not only be relevant to people who have moved from one country to another, it looks like there are lots of resources, especially under the section of human rights groups on the web.
