For anyone interested in immigration rights issues, check out the Capital Area Immigration Rights Coalition (CAIR Coalition). The website is: http://www.caircoalition.org/.
With links to recent articles and an excellent and informative listserv, this group creates a community for people working for and with immigrants.
For example, this recent article http://articles.latimes.com/2009/mar/17/local/me-immigjail17 about immigrant detention centers.
I am grateful to be a member of this coalition, to feel linked to others working to help immigrants and part of a larger community.
