I am trying to apply for a green card for my Japanese mother who reside in Japan. I already filled out all the application but have one question unanswered.
Is there any demerit for her to obtain green card, like U.S. tax duty, any rules on how much time she MUST spend in U.S. to retain her green card, etc?
(She will retire in Japan soon and we want her to be able to spend as much time as possible with our child here. )
Any advice will be truly appreciated.
Thank you very much for reading.
