I don't know how I did that but I forgot to me include a check with my 485 application to USCIS. They sent all my documents back to me with Form-i-797C, Notice of Action. I noticed that USCIS opened the sealed envelope for I-693 prepared by my doctor. Now, when I resend 485 with the check included, do I need to resend a new sealed I-693 or the returned open envelope for I-693 that I received from USCIS work? Thank you!
