I guess we are both first My timeline is exactly the same as yours July 26 mailed, recd at DC on July 28th, received SC and cancelled PP for me and spouse on August 10.!! I have prepared the OCI packet for about 4 times ( believe me everytime I prepared the website would show different rules 3 times after that) and have to prepare the paper work for OCI. I was slacking as I thought SC would take at least a months or 6 weeks but 2 weeks is light speed for DC!!
Cool! Keep me posted on OCI status. I mailed it today.
My problem is that they returned my OCI once already. However, they kept a few papers. I did not make more copies ... just sent all papers that were returned to me, except the stuff regarding SC. I just put 2 copies of SC. Praying that they had the copies of my older documents, including addl pics.
