回复：请问NIW package太厚,用什么才能把它装订成一本呀? thanks....

I think that it is better if you divide them into several package. The central one should be something essential for your application, such as your form, your check, your recommendation letters, etc.
The suppporting package could be your membership, your patent, your paper, etc. If it is still too much, divide them into 2-3 package.
Hope that help. Good luck.
