Not all countries mandate overseas travel insurance for visa purposes. But it is an important thing all travellers must have before they leave for their trip.

Some countries mandate it under their visa documents but even if they do not, all travellers must have a travel insurance. This is because when you are in a foreign land, you may need financial and procedural support in case of difficult situations like an accident, hospitalization, loss of passport or even while travelling like missing your connecting flight, your checked-in baggage getting delayed or in case of emergencies like a death in the family back home due to which your trip needs to be cut short etc... And to be honest, the list of things that can go wrong is quite long but we know you're wise enough to think about all of that and make the right decision related to your and your family's well-being.
