According to the latest changes (1st Jan. 2023) in Indian entry restrictions, all international passengers flying from high-risk countries are required to have an RT-PCR test produced 72 hrs prior to departure and submit the Air Suvidha Declaration. These requirements also apply to passengers transiting through high-risk countries (Singapore, China, the Republic of Korea, Hong Kong, Japan, and Thailand) regardless of the country where their journey starts before coming to any airport in India. Please, however, note that passengers transiting through high-risk countries who will not be crossing immigration are exempted from the requirement to fill out the Air Suvidha and provide a negative test report.
