I'm and Indian citizen, and am planning to go to Malaysia as a Tourist.
What's the official site for applying for the e-visa? A google search leads me to several sites, none of which seem to be the official one.
There are a lot of agents available online. However, http://www.windowmalaysia.my/ is the Official Visa Channel and eVisa Operator for the Government of Malaysia as stated here: https://www.imi.gov.my/index.php/en/main-services/visa/evisa.html.
I have used windowmalaysia myself and got the eNTRI right away. The website is a little buggy but a tad bit cheaper. You don't need an e-visa and eNTRI is sufficient if you are visiting Malaysia for less than 15 days.
eNTRI Note is valid for a single journey into Malaysia for up to a maximum of 15 days for tourism purposes only.
