I just read about this option, would like to know if this is the way to go. I like the idea of having it taken care of. Is there any problems with officials approving this type of visa at a border crossing?

Everybody does it. It is a piece of cake. Just do it online. Fill out the forms and pay. You get a PDF that you print out and put into your passport. For a country that is not exactly highly "connected", they have the easiest visa process.

However, I only went in and out by airports, so someone else will have to tell you about border crossings.

Wait - border crossing - are you going into Cambodia overland? Read all the fine print about the e-visa as it used to be anyway that it was not valid for overland crossings, only for international flight arrivals.

Thanks, on their official website it states it now includes border crossing. I was just hoping to find someone who has used it on this way. We are coming from HCMC to the Bavet/Moc Bai border into Cambodia.

Easy. I stapled it into my passport and removed it at the end of our stay there.
