Group 5 Sponsorship to canada - Srilankan Refugee from India

[karant]

Hi Friends,

I need a help. I applied for Group 5 Sponsorship to canada in 2009 jan. I am having my interview by the end of November 2012.
I have completed my degree in india and working as software professional for the last 10 years.
My date of birth is different in my school certificates than my Birth Certificate.
I dont have birth certificate when i came to India in 1986.
I joined in school with out any certificate. They enrolled me with some invalid date of birth and misspelled my name also.
In 2010 i got my original birth certificate from srilanka with the help of my uncle.

Can i proceed with my original documents or i do have to prepare some supporting documents? Please help me friends..................
