LGBT rights in Guam
Guam became the first overseas territory of the United States to recognize and perform same-sex marriages in June 2015. On June 5, 2015, Chief Judge Frances Tydingco-Gatewood of the United States District Court for the District of Guam ruled that Guam's prohibition on same-sex couples marrying is unconstitutional. She cited the Ninth Circuit Court of Appeals decision in "Latta v. Otter" striking down identical bans in Idaho and Nevada. The territory began issuing marriage licenses to same-sex couples four days later. The Legislature passed the "Guam Marriage Equality Act of 2015" on August 11, 2015, making Guam's marriage laws gender-neutral.
Postage stamps and postal history of Guam
When the United States Post Office Department (USPOD) took charge of the postal service of Guam in March 1901, the local population, soldiers from the US Navy base and indigenous Chamorros, had to use US stamps without any distinctive marks. Since 1901, only a Guam town cancellation indicates domestic posting. This situation is common to others insular unincorporated territories of the United States, such as, Northern Mariana Islands since 1944, Virgin Islands since 1917, Puerto Rico since 1900 and American Samoa since 1899. The existence of a local post at the beginning of the 1930s and the Japan occupation periods were exceptions.
