Border is open between from around 09:00 and 18:00, been advised that should take half a day from start to end of the process. Try to get to the border first thing, to be first in the queue. This is the same wherever you try to cross borders throughout the globe, not always possible I know....
He price has dropped down to €40, plus an additional €10 to a transiteur fixer for the paperwork.
Once you arrive at the frontier, purchase, the you get to the buildings at the start of the Mauritanian tarmac where you get stamped by the Gendarmerie. You then buy a visa if necessary. No passport photos or photocopies needed: they photograph you with a webcam and scan your passport.
