#1. Leave it blank.

#2. If this asks for your residence, put full address. If this asks for your sponsors, putting just the city is okay.

#3. I didn't have to do that when I did mine ( the old form didn't have that part) but I'm guessing it asks for the day and place you filled up the form. Others will correct me if I'm wrong.

#4. You have to put your maiden name.
