1.我是該用AP回美國吧？
-Yes, must use AP.
2.我去加拿大需要簽證吧？
-Yes. You need to use Canada visa to enter US. Check the website of Canadian Embassy/Consulate in US.
3.去加拿大使館簽證我算是什麽身份呢？應該不能再用學生身份吧？應該跟加拿大使館說我是AOS身份？我該交什麽材料證明我的身份？485receipt？還是EAD,AP？
-Any legal status proof such as i-20, F1 I-94, I-485 receipt, etc. Contact Canadian Embassy. Your status type does not matter for the Canadian visa application.
4.我絕對不能用I20回美國是吧？因為我已經表明移民身份，不能再自相矛盾。
-You must use AP for travel.
5.我回來以後就再也不是F1了是吧？
-Your status will be Parolee (and then AOS automatically) after you use AP to enter US. You will get the parolee I-94 at the port of entry when you return. This parolee I-94 is valid for one year and then, you status will be AOS automatically (nothing needs you to do.)
6.我的I94上還是寫著F1 D/s,我那AP入境，跟I94上寫的身份不一樣，不要緊嗎？
-You need to provide/sub-mit the F-1 I-94 to the CBP officer if you drive to Canada or give it to the airlines if you travel by air. Then, you will get the parolee I-94 when you come back.
尤其是第3個問題，我不太確定，比較迷惑，要是我是F1倒明朗了，直接給他們看I20就行了，我現在這個狀態好像沒啥文件可以證明我自己呀？
謝謝。
