Can I choose my English name at will after immigrating to the United States (permanent residence)? Please let me know. Thank you.

English names can be taken at will. As for this question, it is not very important. Take an English name, mainly for the convenience of communication, because when ABC (foreigner) called you, the pronunciation of your Chinese name in English was very nonstandard, and I was too embarrassed to recognize my own Chinese name.

By the way, my friend, when you sign some very important documents, you must sign the Chinese name, that is, spell it in pinyin, not write Chinese.

This question is very interesting. ^_^
