Hi , have anyone gone through name change ( adding surname). I added surname in my name as it was not there in my records. So for this recently I added my surname in Indian passport after publishing advertisement in two newspaper. After this I applied for citizenship and submitted docs like old passport and new passport that shows this is the same person. Now cic requested additional documents like name change certificate. Does Indian consulate issue such letter? What is the process? Please let me know if someone goes through this process of adding surname before applying citizenship with new name.
