Should I be physically present for a police verification if I were to?
I would like to suggest you to please send your query directly to the Indian Embassy in the US as well as to the Passport office in India for the correct clarification you need to have. Or else, you may receive numerous answers in this forum which may be misleading. As I understand, you should be able to renew your passport in US itself if you approach the Embassy. But for changing the address, you may need proof of new address which will require police verification. (Caution-this I my guess work only).
