Most visitors who enter Malaysia are not required to have a visa depending on the nationality. However, it is necessary to check your embassy about the visa requirements before travelling to Malaysia. Regardless if you are required to get a visa or not, please do remember that you need to have a passport that is valid for 6 months after your departure date.
