17岁怎么办签证？
以美国为例，17岁是可以办理赴美个人旅游/探亲/商务签证的，只是要单独面谈，而且不能选择B1/B2 商务探亲签证，必须选B2 观光旅游。 我觉得楼主还是先了解一下签证常识吧~ 美国使领馆官网对赴美签证有非常详细的介绍，可以自己去看看（英文网站） URL 中文网站，也可以参考
URL 签证类型 B1 / B2 Visitor for Business and Tourism. To enter the United States under this Visa classification， visa applicants must be able to prove that they are coming into the US on a temporary basis (less than one year) for business or pleasure with a return home ticket at the time of inspection by U.S. Customs and Border Protection officials upon arrival in the United States.
