I'm on a 1 year employment visa and did my 2nd quarterly visit to immigration a couple of months ago. I know I checked the stamp because I have my next date as a reminder on my laptop calendar. I have scrutinized each page with forensic precision and there is only one stamp that says 2010 and that was thumped in last June when the visa was issued.
No idea what I can do about this, it's Twilight Zone baffling.
