Hello I'm new here and would like some advice.

For cost of living www.numbeo.com
Also a quick flick through this forum will give you some insight.

If the permanent visa you are speaking of refers to the K-Visa, then yes, you will be able to work here without an Ordinary (E-Visa. Formerly called Business Visa) or Work Permit.

There is quite a lot of overseas Khmer, including many that have never been here before, that have returned (by choice or deportation) to Cambodia. I suggest if you have never been before I suggest that you prepare yourself for quite a culture shock. Speaking Khmer will definitely help you though. Do you have family here?

All the best for your move, and I hope that you settle well in your parent's homeland.

Hello thank you very much for the help.
I have been there only twice before. I don't really have any family there so I guess yes it will be a little scary. None the less I did enjoy my time there.

Thank you very much for the support. Will keep a post of my time there. Im sure I'll be ok but I guess it will take a little getting use to.

are u currently in cambodia?

Ok, good to hear that you've been to Cambodia previously, will make it a lot easier on you. Do you know what kind of work you'll be looking for?

I live in PP, but I am currently on a contract working abroad but I am lucky to head back every 2 months for 1 month off work.

Oh what sort of work do u do?

I'm not too sure with work. I thought about teaching English but i don't have a degree or anything. I'm a very fast learner so if I find someone who is willing to take a chance on me in something I've never done that will be great. I will have to start putting myself out there I guess lol.
I currently work as a dental assistant. I guess i wont know about work until i know where I will be settled first. I know wages there are a lot lower but I'm also happy to pick up and be more fluent in the language as well.
