It really drives me crazy, I supposed to exit in mong cai coz its d advise of the school but bcoz I still need visa to go to china so I decided to exit Cambodia instead but the travel agency was so lazy to change my entry and he said I can use it anywhere which I doubted it but bcoz I need to catch my plane so I have no time to argue now when I arrived in moc bai they won't accept it coz its mong cai and not moc bai so I called the guy and the immigration explained to him so he advised me to stay over night here in phom phen while waiting for the revised... I hope they can make it today,.. the new system is very confusing and it seems people in Vietnam like working in immigration was shocked too and confused what to do hahahahah oh well if I will make it today I will keep u update guys
