The Federation for American Immigration Reform, abbreviated FAIR, is a US-based anti-immigration group. They have a website at fairus.org.

How does FAIR describe itself?

On its about page, FAIR states that it:

seeks to improve border security, to stop illegal immigration, and to promote immigration levels consistent with the national interest—more traditional rates of about 300,000 a year.

How does FAIR distinguish itself?

FAIR and other groups stablished under its auspices cover the entire gamut of anti-immigration work: coordination of grassroots activism, lobbying and influencing political leaders, and producing resesarch and position papers. Among anti-immigration groups, FAIR is one of the most widely supported by the general public.
