Useless.
The room B110 is straight ahead when you come in the front door. This place needs a receptionist or some signage explaining what to do! There is no reception, no signage, you just go in and sit with a roomful of strangers and wait. For immigration issues, use the phone outside the room on the wall for info. For citizenship testing etc, they will come pick you up at the *exact* time you have scheduled. Don't be late!
There is absolutely no point in going here because they don't take questions in person they refer you to their website. ðŸ˜
