我刚拿到加拿大国籍。我想问一下如果用中国护照，从加拿大多伦多机场用H4 签证入美国，用加拿大公民卡回加拿大会不会有麻烦? 会不会被加拿大海关查出来，挨骂呀？
这麽做的理由是我们的美国绿卡I140刚被批下来，还在等I485. 我的AP 和H4 都是跟中国护照一起的。我因为刚入加拿大籍，来不及申请加拿大护照和新的美国签证。怕以加拿大公民观光身份进美国的话，I485申请会被撤销。请有类似经验的网友回答以下问题。十分感谢！
1) Should we notify USCIS about the addition of my
Canadian citizenship? If yes, will this update delay
our I485 applications?
2) If I enters the US with his Canadian citizenship
card as a visitor (under the US-Canada visa waiver
program and without Canadian passport), will my I485
application be revoked due to the change of status
from H4 to a visitor?
3) Can I use the advance parole with my Canadian
citizenship card to enter to the US ( Although I will
apply for a Canadian passport immediately, there is no
enough time that I can get the passport before my
next visit in October. )?
4) In the future, can I use my current advance
parole, which was applied using my Chinese passport,
with my new Canadian passport to enter the US without
I485 application being revoked? Or do I have to
reapply the advance parole in order to use with the
new Canadian passport?
Thanks a lot in advance!
