We, the Malaysian Chinese

I am a Malaysian and I want to travel to USA but I was informed that I need a visa but why other Asia countries such as China, Singapore and even Korea do not need it? Because I am a Malaysian, it is an islamic country. Yes, I admit our government is not good, but not all the nation is bad. I am just a student, I am not a terrorist, all I want is to travel to USA. I have family and friends in Malaysia, I will definitely come back to Malaysia. Due to my research, they were so many peoples got denied for their visas application. I started to worry until my friend said, you are not a terrorist, what are you worrying? Yes! I will be having my visas interview this June, I'll try to prove to the officer that I am just a young girl wanted to travel to USA.
