Hi Sumeet, I got my Indian PCC just today itself. They told me it will take 7 to 8 working days, but I was lucky that mine got ready in just 2 working days. I only filled up the two forms given by the Indian Embassy, 6 color photos with white background ( 51mm x 51mm) out of which 2 photos to be pasted on the forms itself - one on each. In addition you need to submit your original passport to them along with the application fees of BHD 12/- (Check the fees in Kuwait).
Now coming to Bahrain PCC - I cannot obtain it until I have the letter from CIC requesting the Minsitry of Interior in Bahrain to provide me the Bahrain PCC or Certificate of Good conduct. So, I believe I do not need to submit it while applying for PR.
I beleive it will be the same case for you. I have found this below information from CIC website for Kuwait PCC:
How to Get a Police Certificate – Kuwait
Do I need to provide a Police Certificate with my Application for Permanent Residence? No
Citizenship and Immigration Canada will send you a letter requesting a police certificate after you send your Application for Permanent Residence. You must bring that letter when you apply for a Police Certificate.
Name of document(s) to get: Good Conduct Certificate
Do I need to provide a Police Certificate for Express Entry?
Yes, but only after you submit your application. When you apply for permanent residence, you will be asked to upload a police certificate. Instead, you must upload a document that states: “I am applying from a country that requires an official request letter from CIC to get a police certificate.”
CIC will then review your application. If it is otherwise complete, we will send you more information on how to get a police certificate. Please read the instructions above for more information.
Note: CIC will not accept police certificates sent by mail for Express Entry applications.
