Your mother needn’t be married to an Iraqi dictator for you to have a hard time with the INS. Take Glory Box, a one-man show in which Tim Miller trains his humorous political advocacy on the plight of his Australian partner, who faces deportation thanks to immigration laws that don’t recognize same-sex partnerships. The show’s creator has a strong pedigree: Twelve years ago, Miller stood up to the National Endowment for the Arts when, caving in to political pressure, the organization withdrew performance funding. And in previous work, Miller has by turns delved into memories triggered by dirty laundry (Shirts & Skin) and thought himself the progeny of Death in Venice’s Gustave von Aschenbach and The Sound of Music’s Maria von Trapp (Stretch Marks). The play runs until Sunday, July 14, and starts tonight at 8 p.m. at Source Theatre, 1835 14th St. NW. $25. (202) 393-3939. (Joe Dempsey)
