父母在國內，我是公民，想給他們申請綠卡。現在有一些關於填表和提交的問題，期待答複：
1 網上我找到的步驟是，父母入境後，網上提交130，同時寄出485/864，附上130收據。另外一種說法是把紙質130/485/864放在同一個快遞包裹內寄出。請問這兩種方式哪種更優？
-No difference. I suggest you put all of the documents (I-130 and I-485) in one package and mail it out. But you had better mail your father's case and mother' case in two separate packages.
2 有的帖子說給父母提交的話，沒有入境90天限製，請問是否正確
-They had better wait for 90 days to apply for green card to avoid potential complication.
3 part 9 #61問學位，是否需要原件和翻譯公證？
-No. Not need to provide this kind of documents.
4 父母都已經退休，part 9 #62工作技能還需要填寫嗎, 寫的話是否需要對應的英文翻譯及公證?
-Yes, just list any work license and certificate they have, indcluding education diploma. Not need to provide this kind of documents.
5 父母入境後和我住在一起，130 表上part 4這個physical address應該寫我的地址嗎?
-Yes. It is the address they currently live, even if it is temporary.
