>>Any tips on getting the visa at CASA?

Hi !! . You will need 3 photocopies of your passport (the page with your details ) . There's an abusive expensive photocopy shop near .
You also need 3 photos of yourself (or was it 2? )
and 100 DH .
If arrive with a car , it will be difficult to avoid the "parking guardians" , which populate nearby .

It takes about 3 hours , and if arrive early (8 AM -9 AM it will be definitely ready by 12) .
At the purest African style .. there's no a queue . just a group of people in the door .
Some of them are military , some of them are Mauritanians , some of them are morocc police ,moroccans triying to get a Visa ,and some of the just hustlers ) . It is not clear who's who , so be cautious !.
You are supposed to give your passport , photos , copies , etc... to someone which CAMES OUT FROM THE CONSULATE BUILDING . Go with him inside ... and then you pay your 100 DH fee (10Eur) .Answer a few absurd questions to the consul herself (Its a woman! ) , and get out of the building.

Get back the Consulate in 3 hours... and hopefully they handle (trought the doors'railings) your passport . As someone said , it is a good idea to have some "sticker" in your passport so you can recognize it from a heap of similar passports .
(note that during the whole operation , you are NOT issued with any receipt of the passport ) . That's ok . -for them- .

The consulate itself is near the Camping (the exact coordinates are in "the atlantic route" section in CS's Web.
Id suggest you to take a cab . They have ridicously cheap fares .

Hope this helps ...
