I know that as a USA passport holder i dont need a visa as i can get 90 days stamp on arrival, but does malaysia have any limits on number on entrys in a certain time period?
i want to use Airasia to get around to laos , camboida etc and it means going in and out of malaysia many times as kuala lumpur is the main hub.
is going in and out alot a porblem?
I used to go in/out from Singapore to Malaysia every 30 days or less... it carried on for about 6 months without ever having any problems from Malaysian immigration.
Especially if you have onward flights booked you shouldn't have any problems at all.
