AFAICS from the e-Visa website, Poipet now appears to be ok for e-Visa entry, so there is no need to apply on paper in Poipet? Am I missing something? BTW, I have just spotted that, WEF 1/1/25 the e-Visa prices have REDUCED to $30 for Tourist and $35 for Ordinary, so these are now the same cost as the Visa On Arrival, although in the past I always thought the extra was well worth it just to avoid the visa melee at my usual port of entry, PNH.
I am aware that Thailand-Cambodia-Thailand is now blocked for a same day bounce at Poipet (BTW that block is reportedly avoidable with a purple hued portrait of Vajiralongkorn in one's passport), but had not previously heard that Cambodia-Thailand-Cambodia is similarly blocked. I'd be tempted to try a portrait of Hamilton. Has anyone had success with that?
