Hi,
I'm about to mail the completed I-693 Form following request of the Field Office through e-mail. Is it alright to use the address they specified (just the generic address), or do I also need to write the name of the Field Office Director who requested? Also, is there an advantage if we request for signature of the receiver, or just plain mail will do? I know my questions sound a bit silly, but I just wanted to be sure since we don't want any further delays in the processing of our requests.
USCIS Field Office
Dallas, Texas
or
Mr. Adam Smith
Field Office Director
USCIS Field Office
Dallas, Texas
Thanks in advance!
