Unfortunately one person from immigration can tell you one thing but then another interpret it a completely different way. Personally I wouldn’t want an overstay of any amount on my record just incase you meet that one immigration officer at the Airport who sees it another way.
Ok so you must be giving information that’s out of date. Things change John and just because you did something 20 years ago doesn’t mean it’s the same now. Giving old WRONG information that was right once is still WRONG.
