Thai 60 day visa

I have just applied for my vietnam visa here in ireland to the uk and its gonna take 3/4 weeks
by the time i get it back i have to leave ireland and dont have time to apply to the thai consulate here for 60 day tourist visa

I will be in vietnam working from june 3-jul 3rd
then i plan to stay in thai from july 3 to aug 17th
so i need longer than the 30 day stamp at airport

Can i apply for the 60 day visa for thailand in HCMC?

There is a consulate in HCMC but if you cant get it there just hop over the border into Malaysia and get another visa for Thailand. Bit of a pain for the lenght of visa you want but at least it will be easy enough to do.
