O-1 is a dual intent visa, as is L-1, as is H-1B, so I have no idea what you're talking about?

Do you know why many sources state that it is not dual intent or that it is "quasi dual intent"?
reply"The noncitizen may legitimately come to the United States for a temporary period as an O-1 or O-3 dependent nonimmigrant and depart voluntarily at the end of their authorized stay and, at the same time, lawfully seek to become an LPR of the United States."
replySeems extremely clear to me.
