In 1812, Mason left his family stronghold of Northern Virginia to attempt making his own fortunes in Lexington, Kentucky. In 1817, President James Monroe appointed Mason United States marshal. Mason was appointed Secretary of Michigan Territory and superintendent of Indian affairs in 1830 by President Andrew Jackson. He held those appointments until 1831, when President Jackson sent Mason on a mission to Mexico. To fill his post as Secretary of Michigan Territory, President Jackson appointed Mason's son Stevens.

Mason became a confidential land agent for the land company in 1831. While in Mexico City on the land company's behalf, Mason discovered that the Law of April 6, 1830 prevented the transfer of Mexican land to foreign companies. On a subsequent  trip to Mexico City in 1833, Mason was able to secure a repeal of the law's stipulation that forbade colonization in Mexico from the United States. Once he accomplished this, Mason resigned from the land company to promote his personal Texas landholdings. Mason continued to expand his landholdings by purchasing 300 leagues from the Mexican government and 100 leagues from individual landholders. To manage his land holdings, Mason employed John Charles Leplicher in New York City as his land office clerk and Archibald Hotchkiss as his attorney. Mason's prosperous land business was soon compromised when his large land  grants were cancelled by the Provisional government of Texas. The revolutionary government repudiated the sales of land made in 1834 by the Mexican state of Coahuila y Tejas, going so far as to name Mason's contract as annulled by them in the First Texan Constitution. His attorney Leplicher then filed suit against Mason in Nacogdoches on February 16, 1835 for alleged unpaid salary. Mason was made commandant of the Nacogdoches District by the Committee of Vigilance and Safety on April 11, 1836 only to resign twelve days later. Mason remained in Nacogdoches for most of the duration of the  Texas Revolution. Mason continued to support the Texas Revolution by paying $1,000 for the schooner "Liberty" for the Texas Navy and advancing $500 for the expenses of the schooner "Brutus". On March 2, 1836, the Republic of Texas declared its independence and organized a government. The following year, Mason attended a session of Congress of the Republic of Texas in Houston, the capital of Texas. Later life. After the Texas Revolution, Mason moved to New York, but returned to Texas multiple times during the 1840s. He traveled to Texas for the last time in 1849.
