Back in March I sent a straight to the point letter asking to switch my petition to a divorce waiver with my divorce decree to the address in the bottom left corner of my Notice of Action I-797. From looking at similar situation here, it seems most people that did the same thing receive a case status history update on the USCIS along the line of "Correspondence was received". I do have the tracking number of when I sent the correspondence.
First question would be: Is this a big deal? Does this happen often and am I safe with my tracking number?
If it's a big deal what can I do? Resend it? Send it to different offices? Call them to confirm they received it? I mean I would prefer to call them to just get my answer but I doubt it's possible, which seems insane to think I wouldn't be able to find that information out but nothing surprises me with this whole process anymore...
Thank you!
