Immglation-Morrocan border
 

I am planning to travel Atlantic route by a bike, want ask about immiglation work at Mauritania and Morrocan border(Nouadibouo).

1)Is it legal to travel Mauritania to Morroco?
2)I heard, at boder post, have to leave your
passport to Morrocan officer then, have to take
officer to Dhakla.

Cause of (2), I thought we need extra seat on
our vehicle for immiglation officer to take
him to Dhkala.
Acturely, how do Overlanders travel clear the
immiglation work? I realy appreciate any
informations.

Ken
