A welcome bonus is a bonus that a casino offers its players once they join their site. It's a way to appreciate new customers and encourage them to play. However, any winnings from the welcome bonus may have to be used to make other bets before any withdrawals can be made.
Laos is a part of the previous Indochina, though the region is not dependent on either India or China. It houses some of the most pristine forests and natural sites of South-East Asia. While mobile online gambling is mostly prohibited, the ban is not enforced on mobile casinos, and many international casinos accept players from Laos.
