My experience with the authorities in Myanmar is limited to getting a visa. However, after working in Yangon for 20 months & visiting the country a number of times, even asking for a social visa, resulted in a phone call from the Embassy in London, informing me that I could ONLY have a tourist visa & would have to stay on hotels. Why? As I am not Burmese.
Living there, I had to leave the country every 12 weeks to renew my work Visa & one was never sure if it would be renewed.
Personnel were always polite but information was lacking.
As a foreigner, one had to be registered for the place you were renting. Once, visitors stayed with me. We were woken up in the early hours, by a group of men, who refused to speak English, demanding to see our papers. My landlord & I had then to visit the local office to pay a fine &  sort things out. Only as I was leaving, did the man in charge speak English.
The experience was humiliating and frightening, ad I could have been deported, just for having foreign friends staying!
As there is no information given, at any stage, one is vulnerable.
Obviously, I had been watched and reported.
Even today, parts of the country are closed to foreigners. They could simply explain that there is civil unrest among ethnic groups but that would affect their image and tourism?
The people of Myanmar are beautiful and polite but the country is, in my opinion still governed by the military, despite so-called democracy.
