在美国申请加拿大签证麻烦吗？

临时出差到美国后，才知道以为N年没见面的很好的朋友移民加拿大了，很希望能去看看他，顺便旅游！方便直接在美国申请啥签证吗？需要些什么材料和程序！！我拿的是B1/B2，M次，1年有效，停留3个月的那种！谢谢！
您有经历过吗？HAPPY!都在美国了，怎么出示那个收入或者资金证明！ ！
好像有朋友说可以直接开车过去？具体是怎么回事？

谢谢PALADIN，专家就是专家！但我想有没有更好的，更方便的！能直接过去吗？
最近有从美国坐车到加拿大的吗？

去这里找标准答案吧！

有美国签证，加拿大的也不难得啊！您应该在国内办好的！的确您没能带财力证明在身边！估计信用卡或者国内传真一个还是可以在美国用！

希望您顺利！
