just, WOW . Sympathies David, you musta been sweating over that one. Totally unreasonable imo that a valid multiple re-entry permit still valid should be invalidated because of a new extention of stay. Of course if following the better safe than sorry philosophy, why didn't you "buy" a new multiple re-entry permit when you got the new extension?
thanks. When my wife collected my passport, she didn't get (for whatever reason) the letter--this some three years ago. I had to talk my way out of it at immigration. Who would imagine a passport needs authenticating?
