I'm a US citizen with OCI. I just renewed my US passport. Is it necessary to get OCI stamped on the new US passport? I do have a valid OCI book. My son, who is a minor, is also renewing his US passport. He has a OCI book as well. Same question for a minor. Would he need to get OCI re-stamped on the new US passport? I've searched and I could not find an answer for this question. Please clarify.
