I am planning to work in China for some time
(one year or longer). I will come back 3~4 times each year and
spend a couple of weeks in the US each time - the time intervals
between two visits will be less than 6 months. Is this sufficient
to keep my greencard? Do I have to stay in the US more than six
months each year in order to keep my greencard?
Thanks you very much!
