If I were you id also book a premium appointment at the VFS which cots 2000 pesos as we just did.
My wife told me there were some applicants there waiting for over 3 hours In queues etc.
I don't know if this is regular or if its just a busy time of year but waiting for that amount of time!
oh and by the way for the TB test people were saying we would have to wait 'til the next day to get the certificate but we got it after 10 minutes of testing and although its better to make an appointment,we arrived a day early and walked off the street and got it done there and then.
