In November 2018, Sadiku was set to compete in the lightweight competition at the 2018 AIBA Women's World Boxing Championships in New Delhi, India. She was denied a visa to enter the country due to India's lack of recognition of Kosovo. India was issued a warning by the International Boxing Association (AIBA) that if the decision was not reversed, the association would withdraw the 2021 AIBA World Boxing Championships from the country, originally scheduled to take place in New Delhi. Sadiku ultimately did not appear on the draw list published on 14 November 2018, and did not compete. This was her second boxing championship event impacted by a denial of entry into India, following a similar incident prior to the 2017 AIBA Youth Women's World Boxing Championships in Guwahati.
