There he worked as an administrator. In 1919 he became secretary of the Dutch embassy in Jeddah in the Kingdom of Hejaz. In 1932 he became deputy consul in Mecca, Saudi Arabia and therefore the highest representative of the Netherlands. Just before the outbreak of World War II he was a senior official in New Guinea.

He was temporarily, the highest authority of the Dutch East Indies in Brisbane. Abdulkadir participated in the restoration of Dutch authority in the East Indies and was appointed a resident (as a colonel in the KNIL) from Maluku.[2]

At the end of 1947, he served as Governor General of the Dutch East Indies and was an envoy of the Dutch delegation during United Nations led negotiations of the independence of Indonesia.
In the Renville agreement, Abdulkadir was an envoy of the Dutch delegation taking place on December 8, 1947. Abdulkadir, signed the agreement, representing the Netherlands.
