Chicx365, I am in the same situation as you but my 601 waiver got Approved last week. My question is, are Walk Ins Ok to bring the approval notice to the US Embassy in the Philippines? Or do we still have to file another ds260?
Wait for a notification from USEM. They will give instructions on what to do and documents that you need to submit. I believe we have to file for another DS 260. Best of luck.
