@Tod ********
It's confusing for the first timers like me.
I always stand and look before leaving the desk area.
Mine went from TR to 90 days O.
Then 90 days O to plus retirement extension.
The retirement extension gives me until March 2019.
Effectively 3 months plus 12 months.
Then the multiple re entry permit was added to this...
I know the stamping filled two pages.
But I always check it...
The first time going out I actually asked at the desk if it was all done right.
They were very nice about it.
Would hate to start again after only six months usage.
