求助8老師，我老公去年8月份為我在國內的16歲的兒子遞交了移民申請。 可是他今年2月份心髒病去逝了，現在我該怎麽辦，我現在是二年綠卡，我有資格繼續申請嗎？
-Yes, you can file I-751 waiver by yourself to get the 10-year permanent green card.

As for your son, has he get the conditional green card yet? If yes, he can do the same way as you to get the 10-year permanent green card.
If no yet, has the I-130 been approved yet? If yes, then you can be the substitute sponsor to take over the I-130 for your son to get the immigrant visa in China if you have enough income.
If the I-130 is not approved, yet, then the I-130 is void. So, you have to file a new I-130 to sponsor your son using F2A category.
Consult an immigrant lawyer if necessary.
