我家的情況跟你的情況一模一樣,問了律師,給的答複是這樣的:“You may ignore the listed priority date as this has nothing to do with the adjudication process of your wife's AOS application. USCIS recently started using these new I-797 forms and some information that is listed is irrelevant. The priority date would only pertain to you and the I-140 petition that would be filed on your behalf. As your wife did not have an I-140 petition filed with this application, you may ignore this listed date. ”
有些副申請人485收據的PD還是空白的,所以無論是空白還是有日期的,都不用去理睬,副申請人的PD是以主申請人的為準的,不用太擔心啦。
