He got the paper on Friday - even the translation

so he is off to Casa in the morning. They told him to give it to the receptionist. Is this the lady at the window on the grounds of the embassy? Or the people across the street from the embassy who check you in? I saw these people taking papers one day, so I am not sure....and I certainly don't want him to give it to the wrong person.
Thanks and I hope everyone has a great Sunday!!!!!!!
