请教8老师, 收到 "Courtesy letter to applicant" for I-693

我今年二月初，给父母递交了I-130 和 I-485， 但是没有同时递交 I-693。 主要是因为体检到二月底才能完成。

今天收到USCIS一封邮件，内容如下：

                                       Courtesy letter to applicant

An initial review of evidence submitted with your application to register permanent residence or adjust status determined that evidence submitted is not sufficient to complete adjudication for the following reasons:

•  A completed and signed I-693 was not submitted.

You will be required to submit information and evidence to overcome the aforementioned deficiencies at a later date. Please follow these instructions:

• If you receive an interview notice in the mail, you must bring information to address these issues to your interview appointment.

Do not mail documents. Mailing documents to this office may result in the processing of your case.

 

请教8老师:

这是RFE吗？

我父母现在没有收到面试的通知，只收到下星期五去打指纹的通知. 我现在已经有Civil Surgon给父母完成和密封的I-693, 我需要把I-693寄到USCIS吗？

非常感谢８老师的帮助！
