So what should we enter for the full middle name. My Green card has middle initial only. In the N-400 application, in the first section where it says "Your current legal name" what should we enter Full middle name or middle initial, and then in the second section where it says "Your name exactly as it appears on your permanent resident card", what should we enter Full middle name or middle initial. Again my Green Card has middle initial only. I will be sending the application in few days. Any advise would be appreciated.
