Hey, so today I got everything ready to go. Printed out all the documents with translations, got the i-485 ready, and went to the doc for the i-693. Basically, I'm all set to send everything out today, except I'm missing the receipt from KCC. I emailed them last night explaining that the receipt got lost somehow and I'm not sure if I even received it. I made it clear that without that receipt, I can't send my docs to USCIS or they might reject my case. This morning, they replied with "The information you provided will be forwarded to the appropriate department." Now, I'm not sure if that means they'll send my request to the right folks and get back to me, or if they'll just pass the info directly to USCIS. So, I emailed them again asking for an electronic receipt or payment confirmation so I can include something as proof of payment with my submission. I have bank transactions showing the payment, but I'm not sure if I should wait for KCC's response, maybe by Monday, or just try to send everything out today.
