1、有没有该带的材料和海关要填的材料的清单？有没有材料我最好现在就填好或准备好？should check Canada immigration website about landing


2、从美国租车过去入关时怎么报？简单说是租的车就行了？
yes.

3、要带照片吗？办枫叶卡或其它材料要用的？
you can bring some just in case. but they will take a picture for you when you apply for 枫叶卡.

4、跟移民官见面时，是不是要一口咬定准备待加拿大？还是可以告诉他们准备返回美国？那样会不会影响发放枫叶卡？
tell the truth. does not matter.

5、财力证明可不可以只用美国银行的美元帐户statement就行了？还是必须要带旅行支票或certified checks？
I took my statement. but they didn't check at all.

6、如果可能，能不能描述一下整个过程，包括入关，跟移民官interview，申请SIN，枫叶卡等手续？
much simpler than you expected.

when you enter Canada, you will not pass through America Customs. In fact, there's no America Customs at all to check you when you go to CAnada from America. When you get back, no Canada customs check you.

bring all the documents you have about your status transfer you made in America, including your family members, in case the america officers check you when you get back. make sure you can get back.
