謝謝8老師回答我之前的問題，再請教兩個問題。
1. 如果I485, I130, I864,I765, I131表裏一個問題不適用，是必須要填N/A嗎？instruction裏麵說“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.”
-Yes or leave it blank.
如果問題裏有（if any），如B2沒有A number就不填？-leave it blank.
但如果問題沒寫（if any）就必須寫N/A？但是我用abode填，發現有些空要數字的話是填不進去N/A的。
2. 網上提交父親的130，但concurrent filing郵寄I485，Part2 的Receipt Number of underlying Petition (if any) 要填嗎？留空還是N/A？
-You cannot file I-130 online if you want to file I-130 and I-485 concurrently. Concurrent filing means put all the documents of boboth cases in one mail package amd mail them together.
You can file I-130 online and then, print out the receipt notice from your account, file the receipt number in I-485 and provide the receipt notice with I-485 filing.
謝謝老師指教
