看到律师发来的140表格，很多不适用的栏目都空着，但移民局官网140表格最新填写指导上写着：
“. Answer all questions fully and accurately. If a question does not apply to you (for example, if you have never been married and the question asks “Provide the name of your current spouse”), type or print “N/A,” unless otherwise directed. If your answer to a question which requires a numeric response is zero or none (for example, “How many children do you have” or “How many times have you departed the United States”), type or print “None,” unless otherwise directed.”

但是也有民间网站说：不适用的地方都空着（LEAVE BLANK）。
请问空着会被移民局退件吗？
