Email Dear xxxxx...

No idea,
Looks but as they requested for passport, that means they will issue visa

Hi eshal,
Dont go so fast, just wait and watch, vfs service is slow so you will get with in 10working days from submission. As per vfs center, maximum time is 20 working days after submission of passport.
