回复：老公要以我的名义买车，但用他的信用卡付，然后他申请bankcrup

Any reputable company will check your credit on both sides of the boarder before it hires you. So, don't even dream about it. US and Canada do share a lot of data.If you want to do that, maybe immigrate to Mexico is a better choice.
Also, dealers generally only take credit card payment to certain amount, several thousands I think.
