我需要给在上海的父母准备B2签证申请资料。
美国驻沪领馆的网站所提供的网上DS156表的地址是：https://218.240.8.118/ds156c.asp
But when I tried to browse to the link, I got the followng warning:
The security certificate presented by this website was not issued by a trusted certificate authority.
The security certificate presented by this website has expired or is not yet valid.
The security certificate presented by this website was issued for a different website's address.
Normally I wouldn't continue browsing, as this looks very suspicious to be a phishing site. Has anyone else seen the same warning? 谢谢！
