British journalist Sami Hamdi is set to be released after more than two weeks in detention by United States immigration authorities. Hamdi, who was held for allegedly overstaying his visa while on a speaking tour, has agreed to leave the country voluntarily and return to the United Kingdom. Advocacy groups and Hamdi's family have argued that his detention was unjust and possibly motivated by his public criticism of Israel's actions in the Palestinian territories. The United States government maintains that Hamdi was in violation of immigration laws, but his lawyer and supporters say there was no evidence to justify holding him without charge. Hamdi's case has drawn attention to the treatment of foreign nationals who have spoken out on sensitive political issues.
