我有加拿大十年旅游签证,持中国护照,如何在加拿大办理美国旅游签证

Applicants for visitor visas should generally apply at the U.S. Embassy or Consulate with jurisdiction over their place of permanent residence. Although visa applicants may apply at any U.S. consular office abroad, it may be more difficult to qualify for the visa outside the country of permanent residence. Visa applications are now subject to a greater degree of review than in the past so it is important to apply for your visa well in advance of your travel departure date.

这断话是从官方网站抄来的。

大概意思就是和楼上所说的一致。

虽然你可以在国外办理美国签证，但是你在本国签证的几率会高很多。

你可以去一个美国领事官方网页填写DS160（DS160是网上的， DS156是纸张表格)

你还需要一张 2x2 英寸的彩照。假如你用DS160， 你要自己上传照片，你填写DS156，要剪出来一张。

我想在加拿大旅游办理美国签证，相对来说，几率还是比高的吧。
