N/A or NA. Should I worry??

My mom says that there are No stupid questions so....
Reading the instructions to fill out the renewal forms (2018 ), It says FILL OUT All questions. If the question doesn't apply to you write N/A (not applicable). The thing is the computer doesn't let you type in the / sign in most of the answers, so should I type NA instead? or leave it in blank?? For example it says write any other names you have used in the past: NA or leave it blank? Im I the only stupid person here that asks this types of questions? or you have a better computer where it let ya type the / sign?. Im using my computer and fedex office computers. Let me know what you guys think here below, God Bless.....

Wrong section buddy, but since I'm here....I literally left all the fields that didnt apply to me blank. You can write NA I suppose. People are going to review and assuming they have at least a high school education, I'm pretty sure they can figure it out

Is not how you think burro! Is how those immigration officials wants it. They can make a note that you used another name in the past as NA. You know what I mean?? Some people have the name Na or Mr. Na so its very important to talk about this type of things in this blog and be united not bitching about everything. we have real smart mouth people here We know that! but let's help each other out as brothers. God bless.... oh and I know this is not the "right" section but just write your point of view thanks

My name is NA, very important to talk about it

I leave non applicable fields blank all the time. Never had a problem with that.

Que te digo. No hay competencias de mensos si no tu fueras el numero uno chavito

I’ve done both, N/A and blank. I’ve never been sent anything back.

However! I fill out in the computer cause my writing is horrible. There are some spots where the computer wouldn’t let me fill in (I think one was alien # actually) so after I print it out I go and fill out anything missing and write it in with a pen. Hope that’s helpful!

I just filed mines a month ago and already got the card mailed to me, i left i.t all Blank

Thanks brother

This is so stupid. You're supposed to leave it blank.
