Better apply for an E category Cambodian visa when entering the country. If you only get a tourist visa, just ONE extension is allowed, permitting a maximum of 2 months in the country. If you believe that's not enough time, go for the E visa, which can be extended for 3, 6 or 12 months.
Nonsense. This embassy is located in Europe, so they IF they choose to accept only EUR statements that's fine but they can't also accept USD statements. Also, Thailand uses the Baht, not USD.
I just made an international transfer to a Krungsri account this morning and it went through in seconds. My last transfer to a Bangkok Bank account about 2 weeks ago took 24 hours, normally it goes through in seconds.
If you're in France, why would they accept USD statements? That's ridiculous! If they're not going to accept AUD statements they shouldn't be accepting other foreign currencies either. No one accepts USD in France anyway.
Extend your Cambodian visa! Another option is, cross into Thailand or another country come back to Cambodia with an E category visa, extend that for 6 months and then you'll have plenty of time to apply for your DTV without worrying about your Cambodian visa expiring.
