These are my personal perspective of your question.
As we know “to” is often used as a preposition in English sentences. So it depends on the meaning the front verb of "to" in the English sentences,as well as the tense of the sentence, e.g. It's time to go to work.（是时候去上班了） “ go to ”means "去".
I have come to Tibet for a long time. 我来西藏很久了。“come to” means "来”
He has already got to this metro station since you woke up. 你醒的时候他已经到达地铁站了。“get to ”means "到达”, ect.
