Hi there! Use a 2 hole punch with a fastener. Sometimes called ACCO fasteners. A punch can be purchased at Office depot for $10. Also use tabs at the bottom of each section. Check the link below. It is instructions straight from the government website.
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 submitting originals unless specifically required.
-Avoid submitting oversized documentation when possible.
