Are there any records of returnees from northern Myanmar?

No, in addition to a fine, you will be detained and have no criminal record, but you will be restricted from applying for passports and exit permits for a certain period of time. North Myanmar refers to North Chinese community in Myanmar. North Myanmar, also known as "Upper Myanmar", is mainly composed of Magway, Mandalay, Sagaing and other provinces and states such as Qin, Kai, Shan and Kachin. Shan State is the main migration place of Yunnan immigrants from China in history, and it is also a complex and sensitive area.
