Hi, there, You wrote the details for how to assemble the immigration documents. It's really helpful, thanks a lot. Actually I am not a smart person, therefore I still have a question: Can you tell me how to use the two holes on the top of paper? You said that don't use fastener. I would like to know what kind of tools which I should use can get the papers together through the two holes.Thank you very much. My e-mail address is lhgu822@gmail.com. Best wishes Huasha
