I did not hire a layer. This guy in our internation of office gave me a list about what i need prepare, then he sent out all documents. This list is very simple, just some normal documents. You need discuss with your boss and internation office firstly, then ask them this list.
The important thing is your boss and the internation offic agree to apply for your GC, then everything is easy, i think.
