Oe_jharpat ji, I didn't see option of paying DS 260 application fee while submitting the form online. It looks like the online payment is disabled for this application (I tried multiple times). So, I sent a cheque to Department of State (DOS) around 7 days ago and waiting for the payment receipt. Does DOS send payment receipt? It looks like I will need to include DS 260 payment receipt while I send documents to USCIS for adjustment of status. Do you have any suggestion for DS 260 application fee payment or sending documents to USCIS without waiting payment receipt from DS 260?
