I have roundtrip way ticket arrive at 15 March 2014 and depart at 28 March 2014, I will attend the TAEEAC 2014 conference, I have registered. As I am Libyan citizen, can I get a visa at the Airport?
My passport Valid until 28 Aug. 2014.
According to Malaysian immigration department as a Libyan you don't need a visa if your stay does not exceed 14 days.
Given that you stay is exactly that much you shouldn't have to apply for a visa. If you intend to stay longer then you will need a visa and likely from the consulate in your home country.
