謝謝您的回答,reentry permit 會打斷continuity 嗎? 就是說五年重新開始計算。
--Irrelevant. If you don't have reentry permit, you will have big trouble when you reenter US if you go forth and back between US and China too often.
但是我是打算每次不到六個月就回美國一次,這樣的操作還是不行嗎?因為這樣可以不打斷continuity?
-I think it works, but you need to have reentry permit.
謝謝
