Buddy,
1. Yes it should be accepted....
2. U can do below which is acceptable:
Alternatives to birth certificate are as follows which is accepted by CIC:
We do accept Secondary school records that contain the following :
Applicant's Name
Date of Birth
Name of Parent/Parents
If you are not able to provide a Birth certificate with all 3 criteria, we require an affidavit stating all of this information or that a Birth certificate cannot be attained.
So 10th standard school certificate or an affidavit containing applicants name, date of birth and Parent/Parents name should be fine in lieu of a birth certificate. Also you must give reason in a cover letter why you were not able to provide birth certificate and that you are providing 10th standard school certificate / affidavit in lieu of birth certificate.
So u can follow the above (make an affidavit with the mentioend info) and avoid the BC to avoid delay....This is completely acceptable to CIC...
All the best........
