Father is in hospital.

Indian immigration won't be allow me in without old passport which containing visa (OCI card linked to the old passport number) I don't know what to do.experts,please advise. Do you think my passport still lying at Glasgow office.thank you

While I understand your question revolves around getting the old British passport back from the Glasgow office, the solution to your issue (of needing to travel to India soon) may depend on Indian immigration practices.

Is it required for the OCI card to be used in conjunction with a specific passport? Can you apply for an e-visa without voiding your OCI? Once in India, can you get your OCI updated with your new passport details?

Many thanks for your reply secret.simon. well, I'm 40 plus age and technically I don't require to transfer the OCI visa to the new passport as long as I carry the old passport (old passport number linked to my OCI)
I rang few times indian high commission and they are not picking up the phone.
Also, I paid secure delivery charge £5 for the return of documents when I applied for the new passport here.

Really appreciate valuable help..thanks

Agree with the above suggestion. OCI holders can get a regular e-Visa and travel in case the original OCI booklet or the passport on which it was issued is not available for travel. This will solve your immediate travel to India.

If HO can't locate your old passport, get them to issue a letter and use that for an OCI re-issue on your new passport. Even this letter is not mandatory - as long as you can provide a copy of the old passport with the U sticker, you will be get your OCI re-issued.

Old passports are sent separately and much later than the newly issued one as a matter of prioritization. The helpline was a bit clueless and contradictory. Best bet to trace the passport is
https://delivery.tnt.com/tracking and use your application number. It should show two deliveries - for British passport and documents.

If the original date for delivery has passed, TNT will just sit on the parcel and someone has to manually adjust the date. You can do this with the above link and I suggest you do that than to call TNT or passport office. My experience was TNT person delayed it further, passport office used the same site.

The 5 pounds just means they send using TNT, who are overwhelmed. Oh, and don't expect deliveries on Monday according to some, but it may also work. Can't pick up from office for "security".

Hope it works out.
