Can anyone check the costs involved on the process to get this "Attestation"? I'm really worried about it. My friend who works at an air company said that they sometimes ask for this shit here in Brazil, and some people aren't even allowed to fly without it. I don't know why, since as clbrun checked there's no problem with the French rules, but people here are just too stubborn. I'll try to get this letter cause I don't wanna take any risks.
