Tnx.Blank page. But if you need more space in a table in origin al form then create a table in the additional page. No specific format.
Also, don't forget to mention that you have additional page for so and so form in your explanation letter.
Since I'm not going to add Use of Representative (IMM 5476) form, I have to write down a letter explaining it. I will add the details of my extra page in the same letter. I was also wondering if the dependent forms should be signed by the principal applicant or the dependent himself or herself.
