Generally speaking from the time your submission leaves VFS for the Embassy. getting stamped then sent back to VFS is quite fast. VFS uses only LBC to return the passports, they haven't been doing a good job lately. One person recently waited 11 days to get their passport back through LBC. Balikbayan boxes we sent, after they cleared customs took a month to get to the Visayas, nobody could ever tell us where they were. Unless you are booking a flight a ways in the future you might want to wait until you get your PP back to do that.
