I did my 90 day this morning. It was so quiet the young trainee on the door didn't even give me a queue number.
The IO scanned my passport, printed out the new slip (30th July) and didn't even give a cursory glance at my form and supporting paperwork.
I then asked when the new office was opening. He said "Another 5 months".
We'll see. But they don't seem to be in a hurry, which suites me as I live barely 4km away. The new office will be a pain.
