'what is your nationality?' vs 'what country do you belong to?'

[Luby]

Whenever we ask someone 'from where are you' he usually tells the place where he live, but if we want to ask someone 'what is your nationality? can we say 'what country do you belong to?' instead or is this wrong.

[Cerberus™]

I guess you could say that, but it somehow sounds a bit more emphatic than you might wish. Perhaps "what country are you from?" is what you're looking for?
