Amnesty International has 50 international offices.  If you come from a country that doesn't have an office you have the option to become an International member. Here, you will receive emails about human rights campaigns that are targeted to your interests and opportunities to take action for human rights impact. You can also become a volunteer, and lead on activism initiatives in your community. Furthermore, you will have full use of the Amnesty International online communities. We can’t do it without you!
