If you don't mind can you share when u applied for surrender certificate and when you received it. Mine i applied Dec 31st and still waiting, it's 10 days in surrender certificate printed stated, BLS tracking always says processing at consulate, i logged a couple of tickets with BLS they just close it stating the same as still being processed at consulate.
Ohh yeah mine was in printed state for more than 10 days. LoL and surrender certificate is just a cheap quality A4 paper. The expensive paper I own right now.
