I will be traveling though China and Vietnam in January and February 2014 and will be spending about a month in Cambodia starting in late February. I plan on taking the bus from HCMC to Phnom Penh. Having read many posts about expats travelling out of VN I was wondering if anyone has any advice on the best way to get a visa for Cambodia. Is this something I can do at the border or should I get one ahead of time? Reading the Embassy of Cambodia website they recommend applying 6 weeks before departure, but I only have about 4 weeks. Any help would be greatly appreciated.
