Bonjour Francis, et bien non, il va falloir aller récupérer les bagages et sortir, puis re-rentrer à l'aéroport ! Il faut donc un visa de transit :
This visa allows you to travel to
India for a very short period in which you can change flights at an airport. You are also able to leave the transit zone of the airport.
Generally, the Embassy of
India issues a visa valid for 15 days, 2 entries. However, maximum stay in
India must not exceed 72 hours for each visit. This visa cannot be exchanged and cannot be renewed in
India. The Embassy of
India,
Paris reserve the right to grant the visa for a shorter duration than that requested. In such cases no refund of fees paid would be made.
Please note: Like all other visa categories, the Transit Visa validity begins from the date of issue of the visa. Should you require a longer validity, you should apply for a Tourist Visa.
et donc aller faire un tour sur ce site :
