Visser attended officer school prior to being sent to Asia. In 1945, he rejoined No. 2 Dutch Troop in India and attended a paratrooper school. In Ceylon, he underwent jungle training together with Raymond Westerling intended to join other allied forces in Asia to fight the Japan forces in Dutch East Indies. However, Japan was surrendered before Visser was sent to the Dutch East Indies. Visser was assigned to be an instructor in a Dutch special forces school in India known as "School Opleiding Parachutisten /SOP" (Paratrooper School). The school was later moved to Jakarta in 1946 and then moved again to Hollandia. During this time he also conducted operations with DST like the South Sulawesi campaign of 1946–1947.
