hi.. i need help regarding TRV application.
My father and mother are applying for TRV to attend my brother's convocation ceremony in canada. while filling the family information form, my father don't have any document which may reveal his father's DOB and Date of Death. Since my grandfather died when my father was only 3 months old and it was in 1950's when there was not any official national identity card or any document which may contain his father's date of birth. Although he do know the father's name as indicated on Birth Certificate. Moreover, my father's eldest brother also migrated to Canada in 1990's. But he died last year, we are not aware about his immigration documents, so there is no any possible way to get the exact DOB. so what i should write in those field?
