>What happens when you are Chinese and your spouse is Canadian and your child is born in Belgium?

Answer: you have a child without a country, without a nationality. 

Seem impossible?

Many countries do not allow children born within their political boundaries automatic citizenship.  The home countries of the parents often do not grant automatic citizenship to babies of parents with mixed nationalities.

Imagine not being able to get a National ID card, no passport, no drivers license.  Imagine having to trace your ancestry back generations to find a relative from a country who does not have residency requirements for citizenship?
