If you're using Adobe Acrobat, you can't even type N/A. In fact if you really have to type N/A on all the unrelated blanks, the form would look ridiculous.

If you want to take it very literally, then just use the name on the front of your Green Card, leaving the middle name blank. Many people leave unrelated blanks empty and it's been fine.

It'll still be fine if you fill in your full legal name as appeared on your passport, because this is a non-issue either way--you'll have to submit a copy of your Green Card anyway, and the officer can see for him or herself.

Thanks for the insight. I was planning to white N/A on all unrelated blanks after printing the form. You are absolutely right, you couldn't type N/A on the form using Adobe Acrobat.

I just use my complete name then, as appeared on my passport as well as the back of my green card. Thank you so much.

Think of it this way: If I were to pick up your green card to find out your name, where would I look? At the front or at the back of the card?

I get what you're trying to imply here. It's just a little puzzling for me, since there is no middle name on the front of my green card, I will be marking the the form with an "n/a" on the middle name part.
