Not sure how you expect them to put it in your passport if you've applied online and not given it to them, but I'd take it as a positive - one less page taken up in your passport!

I got my OA there this year and the staff were fine. Few issues on my side, so I had to go a few times, but they spoke English well. This review just seems like one person’s experience as met a handful of others there who didn’t have these kind of issues.

Also, it was rarely busy so never had to wait, even though I had to book an appointment. They just said turn up whenever.
