顺便罗集了下菲华网其他网友发布关于自己去降签的流程跟费用，希望可以帮到大家：
一、去移民局降签需要的文件：
1.公司开具的离职证明
2.公司的律师写的降签申请书
3.护照原件和工作签证原件。
二、费用：4500P政府发票。
如果没有以上说的前两个文件，这个需要请代理的律师来处理文件问题，大概需要的费用为15000P
四、是否需要回国的问题
降签后将有59天的停留期，到时间了就可以继续续签，这个和旅游签没有区别。
五、降签后是否可以转工作签证？
从菲律宾的规定来说是可以转为工作签的，如果是同类型的签证很方便处理，如果是不同类型的签证就等于是重新申请。
如果是在这边找到新工作的话，最好是按照公司要求来处理，因为每个公司要求都不太一样。我这里不能一概而论。

我的都是公司自动帮忙续签的

这么麻烦

可以
