Please see if we need a "Bai Pi Shu"

Thank you so much!  Our family just got green cards.  My husband needs to work in China most of the time of a year.  He returns to the U.S. every three or four months each year.   In our case, should we apply a "Hui Mei Zheng" or "Bai Pi Shu" for him?

I heard it is for greencard holder who live outside of U.S. longer than a year.  Sorry I don't have Chinese input tool so I have to use English.
