I am sorry but I think your answer is wrong.......You will need to fill Schedule 1 only if you answered YES to any of the questions in the 5257 form under background information.....Please refer to page 4 out of 4 on the application and read the highlited section which indicates what I have mentioned....If you refer to the guide it will tell you the same.......
I might be wrong though.......
