First woman member of Congress
In 1937, the right of suffrage was extended to Filipino women after a law allowing the same was approved via plebiscite. Elections for the House of Representatives were scheduled for 1941. Ochoa interrupted her law school studies to return home and run for the National Assembly representing the province of Agusan. Ochoa handily won the election on November 11, 1941.
Ochoa would not have the opportunity to fully serve out her term. Less than a month after her election, the Japanese invasion of the Philippines commenced, and the National Assembly was unable to convene until it was reorganized under the control of the Japanese in 1943. Ochoa nonetheless tried to perform her official duties as a member of Congress. She was active in humanitarian efforts during the Second World War. After the restoration of the Commonwealth government under President Sergio Osmeña, Ochoa resumed her duties as the duly elected Congresswoman of Agusan.
Ochoa's term expired in 1946, and she was not a member of the 1st Congress that was elected in that year. Still, Ochoa remained in public service, acting as a presidential technical assistant on health to Presidents Ramon Magsaysay and Carlos P. Garcia. She would also help establish a school for midwifery in her native Butuan City.
Ochoa died on September 20, 1978, at the age of 80. She is buried in Butuan City.
