how to 装订 all the materials for my parents green card applicatio

For my parents green card application, if I put all the materials in one envelop (for my mom and for my dad), can they be interviewed at the same time?

Also, how to 装订 all the forms and supporting copies?

Thank you very much for 862811 's great help recently. Happy New Year!
