我已经是入籍了，因为回国2年，当时回国的时候买的是往返机票，结果在国内有事待了这么久，不知道回加的时候会不会被海关问啊？到时候应该怎么说呢？因为有个朋友也是同样的情况，回去的时候被问了很久，但是因为她有在国内的工作签证，所以没有什么。

还有一个关于去美国的问题，如果要去美国那边工作是不是要给加拿大政府说，因为是想过去美国以后再找工作，到底是在那里办工作签证啊，还是去美国不需要工作签证，谢谢

Canadian Citizen can leave and come back to Canada at his/her own will. As per how to answer the questions when passing custom, tell them the truth. That's it.

Working in US, it's not that easy. You may enter the US without a visa since you are Canadian Citizen, but in order to work you must have a work visa otherwise no one will hire you, legally. If I remember correctly work visa should be called H-1 something.
However there is exception due to NAFTA, you may not need your employer to sponse for visa, but it's still hard to find a job there.
Good luck.
