Burmese Citizenship Law-1982 has made the Muslim Rohingyas largest persecuted population groups in the world. Rohingya crisis in Myanmar is a contemporary and crucial issue not only in South and Southeast Asia but also in the world. The „duration of stay‟ of Rohingyas in Myanmar is a matter of controversy raised by Rohingya literatures and Arakanese Buddhists literatures.
