回複：還有一個問題，從加拿大回來，拿哪個護照回美比較妥當呢？這次去加的時候肯定用中國護照。

Since your Canada passport will be stamped when exiting Canada, it would be good to use it to enter US so it would not cause issue when applying for citizenship.  Otherwise your passport will have only a pair of stamps of exiting/entering Canada but no other stamp which indicates you have other passport.

所有跟帖： 

• 謝謝大師，我還沒有申請美國綠卡呢，估計到485 的時候，我已經用過很多次新護照了。 -不耐心不行- ♀ (0 bytes) () 01/06/2011 postreply 15:57:52
