Malaysia Guide
Entry requirements
Nationals of the UK, Ireland, the US, Canada, Australia, New Zealand and South Africa don't need visas in advance to stay in Malaysia, and it's straightforward to extend your permission to stay. That said, it's always a good idea to check with the relevant embassy or consulate, as the rules on visas are complex and subject to change. Ensure that your passport is valid for at least six months from the date of your trip, and has several blank pages for entry stamps.
Upon arrival in Malaysia, citizens of Australia, Canada, the UK, Ireland, US, New Zealand and South Africa are given a passport stamp entitling them to a three-month stay. Visitors who enter via Sarawak, however, receive a one-month stamp. It's a straightforward matter to extend this permit by applying at the Immigration Department, who have offices (listed in the Guide) in Kuala Lumpur and major towns. Visitors from the above countries can also cross into Singapore or Thailand and back to be granted a fresh Malaysia entry stamp. Visa requirements for various nationalities are listed on 
www.kln.gov.my .
Tourists travelling from the Peninsula to east Malaysia (Sarawak and Sabah) must be cleared again by immigration; visitors to Sabah can remain as long as their original entry stamp is valid, but arriving in Sarawak from whichever territory generates a new thirty-day stamp, which can be easily renewed.
When you arrive, you will normally be given a lengthy landing card to complete; note that you need to hang onto the small departure portion of the card for when you leave Malaysia.
