My Oath ceremony is scheduled on July 30th, I may need to travel to India (for good) right after in August 1st week. After Oath ceremony with the naturalization certificate can I travel to India with Indian passport? Will there be any issues while entering India? Will Indian immigration know that I am a US citizen at this time? Can I apply for the US passport(first time) in US embassy/consulate in India with the naturalization certificate? And finally, any issues applying for OCI card and Indian passport renunciation from India.
