Hello mate,
You cannot convert a tourist visa into a business visa within the country. You have to exit Cambodia & re-enter to do that.

When arriving at Phnom Penh airport just make sure you get a business visa rather than a tourist visa. It costs $25 as opposed to $20 (for tourist). You don't need any paperwork, proof of employment, evidence of business - as long as you have the money, you will get the visa. To check you have the correct visa there will be a E (presumably for employment) superimposed upon it. If you have one with a T (presumably for tourist) superimposed upon it, then make sure you get it corrected before you leave the airport.

It's really straight forward & hassle free. Again as long as you pay the money you will get the business visa (or rather employment visa).

This visa can easily be extended for 3, 6 or 12 months from pretty much anywhere in Cambodia

Siamdaze is correct...but just so you don't get confused, the Visa form that you fill out does not have "Business Visa" written on it, it is actually called an Ordinary Visa.

Thanks guys! Sounds like you think it won't be a problem to show up with no paperwork, and they'll hand the business visa over?

Appreciate the responses!

Yes, you just show up and pay your money. You can also arrange for it electronically here: http://mfaic.gov.kh/evisa/

I would contact the embassy to double check that you'll be able to extend the visa though. You can get a business visa at the border without paperwork, however to get a business visa by mail they do require supporting documentation. (In fact they probably technically require supporting documents at the border, but I've never been asked.) You can see details here: http://www.embassyofcambodia.org/visa.html Since they do want documents at one stage in the process, there's a very good chance that they'll also want them in order to extend a visa once you're in the country.

Have you checked what the 90 days residency means for the Russian visa? Does it mean you just have to be in one place for 90 days? If that's the case you could always just do border runs every time your tourist visa runs out; it's an overnight pain-in-the-neck, but you'd be able to keep a mailing address for the full 3 months.

#4 - Your link is of no use in this case. You can only apply for a tourist visa via this link NOT a business (or ordinary) visa as the OP wants.

I've extended business visa's perhaps 8 or 10 times in the past & never been asked for any kind of paperwork. Basically I pay my money & get my extension. It's honestly that easy.

It's generally easy, yes, but it's worth knowing that he may well be playing the odds. Paperwork is pretty fast and loose in Cambodia, but the embassy is pretty clear that they do want paperwork for a business visa. They probably won't enforce it, I agree; I've never been asked for mine either. But it's worth knowing the rules just in case he gets stuck with the one jerk at a desk somewhere.

Re: the link, it also has information about getting a business visa. You're right, it's only valuable for information purposes. You can't apply for a business visa there because they require documents.
