8老師好：
我父親打算近期持B2來美探望母親，我母親已有綠卡，這樣我父親入境會有麻煩嗎 （因為配偶的綠卡）？
-Hard to say, but try to convience the immigration officer at the port of entry that your father will return to China after the short visit.
是否要準備什麽材料。
-If your father does not retire yet or still have a temporay job even if he retired, he may just bring the employment proof with him.
以前總是父母一起入境，沒有任何不良記錄。但母親上次就留下了。
謝謝。
