Is there any GCC affiliated medical centre in Kolkata, India ? Plz reply soon.

Does the PCC need to get attested?? If so, then who is authorised for such attestation?

I have already got the PCC  and Kuwait Family visa. But my medical check up in India has not yet been done.  Can anyone plz tell me that is there any GCC affiliated medical centre in Kolkata?

As there is no Kuwait Embassy in Kolkata, from where should I do the stamping work after getting my medical check up done?

Please reply as soon as possible. Thank you.
