I can get a tourist visa with the span of one month upmost to Vietnam (as of February 2020 only USA citizens can get more than that and I don't hold a USA citizenship).
If I arrive to Vietnam with a one month tourist visa, should I be able to extend it to some more time, say, one more month to six months, inside Vietnam and if so, please detail from experience on how should this be done?
In appreciation of your experience, time and help !
