移民局的要求是在上方打兩個孔，你也可以不打孔，但不要使用釘書機，給移民官造成拆卸的麻煩。uscis的要求如下。
In preparing your packet, please take note of the following:
Do not use binders or folders that cannot be easily disassembled.
Use ACCO fasteners to hold together thick or bulky applications or petitions. Two-hole punching the top of the material for easy placement in the file is appreciated.
The use of tabs assist in locating items listed as attachments. The tabs should be placed on the bottom and not the side for ease in filing.
Avoid using heavy-duty staples; instead use ACCO fasteners or heavy clips.
Avoid ting originals unless specifically required (Forms I-94, Labor certifications, etc). Avoid ting oversized documentation when possible.
