UNHCR leads iBelong campaign, a global campaign to end statelessness. You can make a difference by signing an open letter in support of the campaign: https://www.unhcr.org/ibelong/sign-the-open-letter/. The signature is symbolic without costs to the signee.
In May of 2022, UNHCR hosted a Global Statelessness Retreat in Geneva, Switzerland. Apatride Network was there to provide input on IBelong campaign and its evolution into the new Global Alliance to End Statelessness. You can download UNHCR’s report of the event here.
