No one can know, but reading about peoples experiences in Vientiane there is a clear risk that they will deny you a visa.

No one seems to have had problems crossing by land at Nong khai though, so even if you're denied a visa at the embassy you can get a visa exemption 30 days. But if I was you I would rather try another embassy than the one in Vientiane.

What kind of background check? Are you also expected to show that you can finance yourself for a certain time?

I am there right now and can add some info if you plan to come here.

They only allow 130 visa applicants each day. I arrived 09.15 (they open 09.30) and there were probably 70 people already in line. The line kept growing behind me so get here early if you want to be sure to be let inside!

They also do not provide any forms or copyservice so be sure to have all your documents ready before getting here.
