In 1828, after his second marriage, he made his first voyage abroad then practiced law in Boston for a time. He sailed for Canton in 1833 on behalf of opium trader John Perkins Cushing, settling for some time in Macau where Lady Elizabeth Napier, wife of British emissary William John, 9th Lord Napier, found him "very intelligent". While he was there, his portrait and those of three of his four children by second wife were painted by the English portraitist George Chinnery. In Asia, he entered a succession of trading firms, and in 1842 he became a full partner. In 1844, Sturgis retired to Boston to rejoin his children who had been sent there to school after their mother's 1837 death in Manila. He married, for a third time and decided to return to China with his family in 1851. The steamer on which they crossed the Atlantic arrived too late to catch the onward ship from London. In their interval there, Sturgis was asked by the senior member of Barings Bank to become a partner. He accepted and ultimately became head of the firm, succeeding fellow American Joshua Bates. In England, he lived at 17 Carlton House Terrace in London, and Givons Grove in Leatherhead. Although he never renounced his U.S. citizenship, Sturgis did not return to the United States and died in England in 1887.

Before her death in Manila on September 17, 1837, they were the parents of four children, the youngest of whom died in infancy:
