2009年以前此类移民肯定是就此完结，但在2009年奥巴马签署了一个补救方案，可以让死者亲属继续申请绿卡，

即：Basic Eligibility for Section 204(l) Relief for Surviving Relatives

其中对主受益人死亡后，有这样的规定：

You may be eligible to seek relief if you are a:

Derivative beneficiary of Form I-130, Petition for Alien Relative (regardless of whether the petitioner was a U.S. citizen or lawful permanent resident), and the principal beneficiary died;

但要满足“在美居住条件”，即 Residence for the Purpose of Section 204(l) Relief Eligibility

具体要看楼主的case是何种情况。

例子一个：

Mr. Nowak is sponsored for permanent residence by his U.S. citizen brother. After the I-130 petition is approved, Mr. Nowak waits many years for his priority date to become current so that he can file his application for permanent residence. Unfortunately, Mr. Nowak dies before the priority date becomes current, leaving behind a wife and two small children. Under section 204(l), Mrs. Nowak and the children can still apply for permanent residence based on the approved I-130 if they meet all remaining requirements, despite the death of the main beneficiary.
