俄罗斯voucher/Russian Voucher

最近要去俄罗斯玩，办理旅游签证的话一定要一个邀请函Voucher。

网上搜索之后，发现在http://www.russieautrement.com/可以免费办理，只要在自己的博客上宣传一下就好了：）

For anybody who is going to Russia, a voucher is necessary for the visa. After researching on the internet, the website http://www.russieautrement.com/ appears to be able to deliver good services for obtaining the vouch.

I will send my document to them now and keep you updated on the application.
