External Affairs Minister S Jaishankar has revealed why Indians are not allowed to hold dual citizenship. He said there are several economic and security challenges in providing dual citizenship, but added that the debate on the same is “still alive”. Jaishankar also said that the Overseas Citizenship of India (OCI) programme is a step to bridge the demand. While many countries like the United States, Canada, Israel and even Pakistan offers dual citizenship, the Indian constitution does not allow it.
