需要上面的这些材料，产生很多问题，麻烦GGJJ帮忙做下解答

关于双认证的办理：

1.外事处认证的时候，必须去北京办吗？还是在自己省会城市的外事处认证就可以？
2.外事处认证的时间大概是多久？前辈们有的回答两周，有的只需要6~7天就OK了，能给个确定的答案吗？
3.在大使馆认证的时间大概是多久？当天可以办下来吗？

关于取签证的问题：

1.去大使馆取签证是否需要预约？
2.在荷兰是否需要办未婚双认证和无犯罪记录双认证？


小弟在这里谢谢各位前辈了

至于双认证的问题 你可以直接联系位于北京的留学中介，外事处和大使馆的他们都可以给你办了费用一共大概500左右，时间大概2周，去北京取签的时候可以一并去中介拿了，去大使馆取签要前一天去预约，第二天去拿，预约时把资料都递，剩下的就是按照他通知的时间去取了，如果早上去预约的早，很可能下午就可以拿了。看你运气了。祝你好运！！
