, some notes about Phnom Penh, they like that you use agent. But Embassy is hardcore. Why? It is not because the few foreigner that apply. It is in fact the thousands of Cambodian that apply visa under MOU agreement, so Embassy has basically no capacity for "real or fake tourist". You will often see people mention certain shops to use, but they also give passport to the real agency, I assume there are 3. We used to deal with one of them, but even this does not give an "positive" outcome. Phnom Penh also have the attitude to collect payment with application and than void, while keeping the money. A place to be avoided. If you just plan to stay a limited time and you have not used the allowance of 2 land border crossing, use one of the friendly border to enter Thailand on 30day visa exempt. Ban Laem, Ban Pakkard or Had Lek is OK.
