Pergunta: Será que o profeta Néfi visitar Joseph em algum ponto no tempo?
Question: Did the prophet Nephi visit Joseph at some point in time?
Several of Joseph's associates believed that Joseph had visits from both Moroni and Nephi during the process of the Restoration
George Q. Cannon in 1869,
If you will read the history of the Church from the beginning, you will find that Joseph was visited by various angelic beings, but not one of them professed to give him the keys until John the Baptist came to him. Moroni, who held the keys of the record of the stick of Ephraim, visited Joseph; he had doubtless, also, visits from Nephi and it may be from Alma and others.” 
John Taylor notes in 1877,
Who was it that administered to Joseph Smith? Moroni and Nephi, men who had lived upon this continent. 
President Taylor repeats this assertion in 1879,
Afterwards the angel Moroni came to him and revealed to him the Book of Mormon, with the history of which you are generally familiar, and also with the statements that I am now making pertaining to these things. And then came Nephi, one of the ancient prophets, that had lived upon this continent, who had an interest in the welfare of the people that he had lived amongst in those days.
