HELP!Already Mailed documents after Payment of IV-new coversheet

[glemette 2]

My husband just paid our IV today then he received an email containing a different cover sheet.

We already mailed our documents yesterday, what should we do?

The coversheet contains this message;

F2A

The next step in the immigration process is for each applicant to submit an Application for Immigrant Visa and Alien Registration with supporting civil documents. A link to the instructions has been provided on the Receipt Page. You can also find the instructions through the NVC website at www.ImmigrantVisas.state.gov. You MUST RETURN THIS COVER SHEET with the completed forms and required documents for the following individuals: (my name & my 2 daughters)

Failure to do so will delay your visa(s).

Please attach this page to the front of the documents for this case and mail to:

National Visa Center

Attn. CMR

31 Rochester Avenue Suite 100

Portsmouth, NH 03801-2914

Also the ”ATTN to” is somewhat different from the email to in the NVC web site

National Visa Center
Attn: DR
31 Rochester Ave. Suite 100
Portsmouth, NH 03801-2914

Don't worry about it. I was instructed to submit my documents with just the AOS barcode. They just need an official barcode with the case number on it. So you are all good!

Thanks, we’re just so afraid that this incident will cause a delay.

I hope that everything will work smoothly

This journey is really stressing me out
