It is very painful for a person to lose his nationality.

Losing one's nationality means not being recognized as one's own citizen by any country in the world now, and being deported after being discovered means being isolated by society. I also lost all kinds of political rights. In today's world, except for the high seas, all places are basically occupied by a certain country, and deportation means losing a lot of living space!

Of course, if you have the ability to survive in the sea or virgin forest, and you happen to like this kind of life, it is estimated that it will not be very painful. If you don't like it, then .........

Personal opinion!
