After moving to Bangor, he continued the practice of law and became a member of the Maine House of Representatives (1835-1840), serving as speaker in 1838. Elected as a Whig to the Twenty-seventh Congress (March 4, 1841-March 3, 1843), Allen was an unsuccessful candidate for reelection in 1842, but was again elected to the Maine House of Representatives in 1846.
He moved to Boston in 1847 and resumed the practice of his profession. Elected to the Massachusetts House of Representatives in 1849, he was later appointed consul to Honolulu in 1850 and was prominently connected with the government of the Hawaiian Islands as chief justice and regent, and as envoy to the United States in 1856 and 1864. He served as minister from the Kingdom of Hawaii to the United States from 1869 until his sudden death January 1, 1883, while attending a diplomatic reception given by President Chester A. Arthur in the White House at Washington, D.C., with interment in Mount Auburn Cemetery, Cambridge, Massachusetts.
