Go to their e-visa website, fill out a form, upload a picture, pay $40 with debit/credit card and then wait a couple days for approval. Good for a 90 day stay. Brilliant. Note: it does kinda suck to drop $40 on a visa for a 1 week stay but this trip will be more of a short scouting trip to see what me thinks about the country/culture. I do have some questions about what it takes to get a Filipino to Cambodia. I see they are exempt from having to get a tourist visa. Can they just show up to any entry point and be granted entry with no hassle? I think the biggest problem will be getting her out of the Philippines. So what will a single Filipina that has never traveled outside of the Philippines need to do to get out of the country with as little friction as possible? She will be showing up in Manila with a valid passport, round-trip ticket to Cambodia and several hundred USD of cash on hand + an ATM card that works overseas. Other than the exit tax/fee is there anything else I'm forgetting or need to know? Can she go to the DFA at Robinsons and fill out any paperwork/pre-register the trip or anything like that?
