前幾年公司幫我申請綠卡，自動把我孩子也申請了綠卡，現在孩子不願過來， 老婆也不願意過來. 兩年也就偶爾周未過來， 現在孩子在加拿大上大學，我說既然不過來， 就主動取消算了， 老婆說不主動取消，反正不來，就看海關什麽時候自動吊銷綠卡。
-Your wife and kid had better file I-407 to abandon their green card. Then, they can visit you using their Canadian passport as visitors.
我孩子剛18歲，要主動取消嗎？
-Yes.
我老婆如果取消綠卡退休時還能拿美國我的ssn嗎？
-Yes. When you retire to get your SS retirement benefits, she can have the spouse retirement benefits after you retire when she reaches the retirement age (62 for early retirement, or 66-67 for full retirment).
家人都在加拿大
