Ok, Yes this makes sense.. Also did you also get two payment links, one from CC Avenue another Auto generated mail from VFS. How much time after making payment you got the AWB number mail.
It was all handled by Lawyers, did not get any update in between, Just waited patiently; all in all usual processing seems to be 4W + Few Days after Biometrics
Yes, my lawyers asked me to get it upfront as a requirement. There are alternatives also if you are not able to get it. Try to get it from one or two employers at least. You can search Youtube and many people have explained the format also.
It is single letter with details of your roles and responsibilities along with compensation at the time of leaving, you have to get it from previous employers.
