I just obtained a visa for China in Paris, on my French passport. It took 3.5 days (including 2 days to get an appointment).
Much to my surprise, the price was 175€, when I expected 85€ (including 25€ for express service) based on the price listing at the Chinese Embassy's website and confirmation there. But on the invoice was extra 66€ for service charges, 24€ for express, and 15€ for 20% VAT on these two extra. The invoice mentions a company called China Bridge.
Did I have a way to get my visa at nominal cost?
Note: I applied for my visa as suggested by the Chinese Embasy's website. I was unaware that I was applying thru a visa application service. It is linked from the Chinese Embassy's website (which itself is linked by a French official website) as the official way to apply. That China Bridge seems to have been officially appointed.
