我要申请去德国三个月以上学术访问签证。邀请信上说明The cost for the stay, including health insurance financed by a grant from the Max-Planck-Gesellschaft. It covers the costs of the usual living expenses including housing and health insurance and is 2100.00. € per month. 我不知道申请签证的时候还需不需要另外办理保险。
另外，RK 1200申请表用什么语言填写？英语可以吗？ 谢谢！
