Don't immigrants miss their homeland?

A person who emigrates to a certain area abroad to settle down. Immigrating to other countries does not necessarily mean that you can't return to your hometown, but that you have multiple choices in life, and you can choose another lifestyle and environment. However, if you miss your motherland, you can still choose to come back.

The right of permanent residence is essentially a right, which enables residents who have obtained permanent residence to live permanently in all countries and enjoy the same treatment as nationals of the host countries in many aspects. The English of permanent residents is permanent resident, so it is often called PR. Usually, permanent residents are represented by visas. In Australia and New Zealand, a permanent resident visa is usually affixed to the holder's passport, while in the United States and Canada, permanent residents will get a special travel document, which is usually called a green card because it is green in the United States. This is probably the origin of the word green card. In other words, the green card is only applicable to the United States. In Australia and New Zealand, there is no green card, which is usually called permanent resident visa and permit, while in Canada, it is called permanent resident card.

Obtaining PR usually does not automatically acquire the nationality of the host country, so it does not automatically acquire dual or multiple nationality for nationals of countries that allow dual or multiple nationality. Similarly, for countries with single nationality, their original nationality will not be lost. At present, China is a mono-ethnic country. China citizens will not lose their China citizenship after obtaining permanent residency in other countries, but will continue to hold China passports and have the qualification to live in other countries for a long time.
