Border policies are not stable. Travelers report that Cambodian visas are available at the border but Laotian visas are not available at the border.
Border crossings with Vietnam
Cambodian visas are available at the Moc Bai/Bavet and 'Chau Doc' border crossings. Vietnamese visas are not available at any overland border crossing
Border crossings with Thailand:
Cambodian visas and 30-day Thai transit visas are available at all Thai/Cambodian border crossings. Thai transit visas are free of charge. Other types of Thai visas are not available. At the Poipet and Kohkong crossings, Cambodian immigration usually charges 1000-1200 baht for a tourist visa and 1500-1600 baht for a business visa. Unlike the rest of the country, they usually refuse dollars. At current exchange rates, the price in baht is significantly more expensive than the official prices of $20 and $25. Some people have had some success paying the official price in dollars by being politely insistent.
