本人為在美國的H1B，由於種種原因無法通過公司提出EB綠卡申請，一年半以前父母通過其他子女取得綠卡後為我遞交了I-130親屬移民申請，主申請人是父親，現在還沒有批準。現在他們都已經入籍，如果考慮將案件從FB-2B轉為FB-1並Carry Over之前的優先日期，需要如何操作？是等之前的I-130批準以後，以現在公民的身份再提交一份I-130，在I-130首頁上注明"Case for Priority Date Carry Over"並附上已批準的I-130嗎？
-Your father can write a letter to the USCIS service center where the I-130 is located to request the I-130 be upgraded. Enclosed the copy of his US citizenship certificate and the I-130 receipt or approval notice.
Another choice is: do nothing because the upgrade will be done automatically and then, you just file your I-485 when the your priority date becomes current based on FB-1 category by providing the I-130 receipt/approval notice and your father US citizenship certificate (equal to I-130 upgrade and I-485 filing at the same time).
看到很多案例因標注不清申請被退回，具體該如何標注呢？另外，這第二份申請還是要再交一遍申請費的吧。還有就是如果Carry Over成功的話那麽收到的Receipt上標的就是上一份I-130的優先日期了吧？
另外還有一個棘手的問題，我的父親目前查出患有癌症，為避免申請過程中出現意外，第二次可以由我的母親為我提出申請並Carry Over以前已批準的由父親為我提出的I-130的優先日期嗎？
-No. The two I-130s are irrelevant each other. If your father passes away, the I-130 (he sponsored) automcatically is revoked. However, if your father passes away after the I-130 is approved, you might still reinstate this I-130 by finding a "subsititue sponsor". This is a nother subject and I do not want to discuss here.
