Can I get a business visa wile still in Cambodia on a tourist visa?

I am in Siem Reap now and plan on heading to Bangkok on the 25th (the day my 30 day visa runs out) can I get a 6 month to 1 year business visa without leaving Cambodia?

No you cannot, you could just pay overstay fees, $5 per day. Next time come in the correct visa and then have it extended.

Hi  APPARENTLY IT IS NO LONGER CALLED A BUSINESS VISA ..... ITS CALLED ORDINARY VISA .. DONT ASK ME WHY BUT TWO PEOPLE HAVE SHARED THIS .. ONE WHO WAS REFUSED AT TWO PLACES ENTERING FROM LAOS  BECAUSE HE ASKED FOR BUSINESS VISA ... SO TOURIST VISA AND ORDINARY VISA IS THE  LATEST
