Transfer Of Indian OCI From Old Passport To New Passport

Hi everyone

I need to transfer an OCI from a expired British passport to a new British passport. After spending a good few hours on the OCI website, I can only describe it as very unclear and not exactly easy to gather all the information unless you scour multiple pages.

Anyway, I have now done the following:

- Applied for OCI Misc services and completed the online form
- Uploaded a signature and photograph
- Uploaded the supporting documents (new passport photo page and proof that person is no longer employed)
- Booked a appointment at Goswell Road

If I understand correctly I also need to provide the following:

- Photocopy of "ALL" pages in the OCI booklet
- Photocopy of photo page in new British passport
- Photocopy of photo page and OCI page in old British passport
- Photocopy of all pages of the completed application form that was printed out
- All photocopies must be self-attested

Finally, how many self-addressed prepaid Special Delivery envelopes do I need to provide if i am going to Goswell Road (London branch) to submit my documents. On some websites i am reading only 1 prepaid envelope is needed however the VFS website says 2 envelopes are needed. If someone could clarify thats would be great.

Thank you
