According to posts on social media, the immigration authorities are now asking for proof of retirement from your home country before issuing ER visa extemsions (otherwise known as retirement visas.) This obligation is said to have come into force on 29 September 2017 (last Friday.)

As usual, it is not clear if this applies to everyone all over the country, and whether the application of this requirement will be strictly enforced. It may also turn out to be a rumour. Also unknown is whether or not this applies to both 6 and 12 month visa extensions, and exactly what documents will be needed to satisfy Cambodian immigration.
If anyone has first hand up-to-date information (from 29 September)on obtaining an ER, please share.

No idea, What's an EG?

For people who aren't working but are (supposedly) looking for work.

I have never heard of an EG visa.
If you want to look for work then you need an EB visa.

EG visa. The EG visa is intended for those searching for employment, and can last 1, 3, or 6 months. At the time of writing, the employment requirements are not strictly enforced for the EB visa, so the EG visa is redundant, but if in the future the requirements for the Cambodia EB visa become more strict, the EG visa will be useful for new expats looking for a job.
