I am applying visa for my parents, so it is supposed to be two visas for them, right? Now I have downloaded the application pdf file and print it out. I found there were two 'application for a visitor visa' forms. So I understand it's one for my dad, the other is for my mom. But there is only one 'Family composition information' form, and whom should I put into the 'Visa Applicant' blank on this form, my dad or my mom? Besides, there is only one 'Details of Education And Employment' form, whom should I put into this form, my dad or my mom? Or maybe I should copy these two forms and put both of my parents into them?

Thanks a lot.
