Hello forum brothers and sisters
Having noticed quite a few concerns, questions and rejection by CIC for issues related to Birth Certificates, I would like to share my experience and try to address the issue here.
Please note: If you manage to get what is mentioned in point 01., then you do not need anything else. If you do not get what is mentioned in point 01, then ALWAYS remember that you would need more than one of the remaining mentioned evidences and they would all have to be clearly labelled and communicated to CIC that they are being submitted instead of a BC and thus should be respectfully considered.
01. In the event that your BC is not available, it is FIRST advisable to try to get a BC issued LEGALLY. I am stressing on this because there are very high chances that CIC does background checks and could usually send the BC back to the BC issuing authority for verification. I know QUITE A FEW cases where fake BC was not verified by the BC issuing authority, it was also confiscated by the BC issuing authority and CIC and USCIS (US Immigration) refused the cases on the base of fraud and lying.
02. If above fails, try to get a "Certificate of Non-Availability" from the concerned BC issuing authority. They might or might not issue this in the first place because some authorities might say that they are not even sure, if you were born in their jurisdiction.
03. Hospital birth records which name the person and the parents.
04. A doctor's or midwife's certificate.
05. Medical records which name the person and the parents.
06. Immunization records from your local health clinics or health authority (I personally used this for me and my brother. He is US citizen now).
07. School records which name the person and the parents or atleast one of the parent. These can include school leaving certificates, 10th certificate, 12th certificate, mark sheets and/or a current letter from your first school or college stating that in their records, they have your name, father's name, mother's name, DOB etc.
08. Census records
09. Church records
10. Adoption decree for adopted children
11. 1 or 2 or 3 sworn affidavits by people who were living at the time of your birth and who have personal knowledge of the events such as your date and place of birth and the identity of your parents. The persons making the affidavits may be your parents, relatives, neighbors, family friends or just about anyone who can confirm the facts related to your birth. The persons making the affidavits should also include their: full name, address, their date and place of birth, their relationship to you, information regarding your birth event, and information as to how they know about this. For example, in my very own case my father's brother wrote an affidavit for me and he put all the above mentioned details and wrote that when I was born, my father and mother immediately informed him of the good news of my birth over the phone. SIMPLE and TRUE statement AND ACCEPTED AS WELL.
The best and lethal combination to ensure acceptance by CIC or other authorities is to include 1-2 affidavits and a couple of other evidence mentioned above. Hopefully it should be admitted without any questions by CIC.
