Paying for the premium service is an individual preference, and we go for it for different reasons. Firstly, the HR office where I work has an annual visa-check on me to ensure I'm legit to stay and work here. Secondly, we've already booked our flight in May, so I really need my passport back. Lastly, I don't want to torture myself with worries thinking will I be granted a visa or not......I saved monthly for this visa.
