The answer is you can have as many as you want, depending on your original citizenship. While some countries allow dual citizenship or many citizenships at the same time, others do not and require you to renounce your previous citizenship.

China doesn't allow dual citizenship, but Russia does.

This is another reason why Russia wins.

In any case, if Elon decides that he wants to be Russian too...
