回複：投資移民沒有移民監，這個可信嗎？

every GC holder is the same (except military or diplomat deployed abroad by official order, or people with approved N470, then they will be considered residing in USA even when deployed.)
you can defer the 移民監 later by getting reentry permit. 隻要每年2次登陸美國（住幾天無所謂)即可 can work for every body for one year (or two), but not in the long run.
