You have to put it in a way that will make it easy for them to open and read.
You don't want them to start looking at your case with a grumpy face because of difficulties to open the envelope,
or a "staple cut" on their fingers....
Make sure that every page has the "sponsored" name/date of birth/ document reference number (Form nbr, question nbr...)
try to imagine that the package will blow away, and you want to make it really easy for them to put it back together...
Don't forget to photocopy the whole package once is ready...
