Greetings,
First of all, depending on what you intend to do, a specific visa is needed. An Internet-based operation is not affected by local taxes. And the services here are good enough to be successful. Also, if this is the case, you only need to know the languages of your client base.
Otherwise, Malagasy prefer Malagasy over foreigners. Fact. I drove a motorcycle for years, but any time there is a problem with a local scooter, <I stay away because <i nwo my insights and experience "are not applicable" in Madagascar, as was once pointed out to me during a workshop with experiences drawn from 60+ countries.
