Well my understanding is the issue is about getting to the airport and not crossing the border per say.
I don’t think it would come to that anyway. You just have to make up a “business letter” stating you are urgently required to attend an executive business meeting in Copacabana or Cancun. It’s all highly confidential so you can’t discuss further.
