thanks. I don't think I will apply for the US citizenship later, so it is not a problem for me. The major concern is that if it may cause any problem if I use my Canadian passport and green card to travel aboard and come back. I suppose the database will show my chinese citizenship(which
would be invalid according to Chinese law) if they decide to screen it.
