I arrived in Bangkok today and was not asked. However, I had already bought a flight forward ticket just in case. I was asked in Indonesia, Malaysia, and Singapore over the last two months.
Someone else recommended buying a cheap train ticket. I found one for $7.00USD from Nong Khai to Vientiane Laos. I didn’t need it but for $7.00 it was worth the peace of mind.
OMG you guys are making my day!!! Everything I was reading online and on their website was saying I need to apply for the E-tourist visa in advance. I was so nervous about it I guess I was overlooking the obvious. This group is the best. Thank you so much!!
