Should I convert my Indian passport to a Hong Kong passport before?
India does not allow dual citizenship, how you can convert your Indian passport to Hong Kong passport? If you somehow do that then you need to renounce your Indian citizenship. However, in my view changing your passport (if that is legally possible), has no effect for getting admission to the universities or eventual student visa from US, Canada or UK. If that is the case then why you want to change your passport? May be you may like to inform us why you want to do this?
