If you are travelling to Malaysia as a tourist or for social or business purposes, you may not require a visa for a period up to 3 months. Countries that do not require a visa include most countries of the European Union, the USA and many Commonwealth members. Citizens of Afghanistan, Israel, Serbia and Montenegro, however, cannot enter Malaysia without approval from the Malaysian Ministry of Home Affairs.
For information on whether you need a visa consult the website of the Malaysian Ministry of Foreign Affairs. There you will find a list of all countries and their respective visa requirements. All information you need is available in English.
Irrespective of what type of visa you are applying for, you must have a passport with a minimum of six months validity remaining. Apply for a respective visa at a Malaysian embassy or consulate in your home country. You will have to pay a fee that will vary from country to country. Furthermore, if your nationality or your travelling purposes require a visa, you must have a sponsor in Malaysia who has to agree to be responsible for your maintenance and your return to your home country.
After arrival in Malaysia
Upon arrival in Malaysia you will be required to present proof of sufficient financial funds to stay in Malaysia for the period intended as well as a valid return ticket. In addition, you will be asked to fill out an Arrival/Departure Card which is available at all entry points.
Note that Malaysia consists of two parts, the peninsular West Malaysia and East Malaysia. To travel from one part to another, travel documents are required.
