A congressional delegation will visit Guam next week to discuss the proposed relocation of 8,000 Marines and 9,000 dependents from Okinawa, Japan to Guam.
The delegation will also conduct a public hearing on the military buildup.
The Pacific Daily News says the visit coincides with Secretary of State Hillary Clinton's first trip to the Asia Pacific region.
Mrs Clinton is expected to meet with Asia's heads-of-states from Japan, Indonesia, the Republic of Korea and China.
Her trip spans a one week tour of the region.
House Speaker, Judi Won Pat, is hoping that Mrs Clinton will have time to meet with Guam officials to discuss the military buildup and other matters concerning U.S.-Guam relations.
