办五年多次往返签证？
先占个位，回头补充 个人认为，目前主流的签证有四种(以申根签为例) ： 单次（Single entry）、 两次（Double entry）、 多次（Multiple entries， sometimes also called a multiple visa or multi-entry visa. )和 永久（Permanent/lifetime visa， also known as ‘10 year’ visas’) 这四种类别中，前2类是相对简单的类型，而最后2种则是难办的类型了。 接下来分别介绍一下这些签证的适用对象及特点：
A Single and double visa (B， C & D categories are not included here)： This is the most common type of visa used by travelers going to Europe for holiday purposes， usually with their families. There are two main types： A-type is valid from one month up to twelve months; B-types start from three months up to six years.

B Multiple Visa： All the tourists who travel frequently around Europe may request this type of visa – it is divided into two subcategories according to its duration： Short term or long term. For short term， there are four different kinds： five年多次往返（valid for five years)， ten年多次往返（valid for ten years)， fifteen年多次往返（valid for fifteen years)and lifetime visa. It covers your travels throughout European Union countries plus Iceland ， Liechtenstein ， Norway 和 Switzerland . Here we focus more on the latter kind ： lifetime visa， because these visas are very complicated and difficult to handle. The first thing that distinguishes between different kinds of multiple visas is how many times you can reenter Europe while holding the visa： 5年多次往返：you can exit and reenter once every twenty eight days during the whole validity period. 10年多次往返：once twice a day during a
