Looking for advice for obtaining US B2 visa from Thailand:

I am a Brazilian citizen and I was selected for a short course in the States in mid May. Would also visit some friends while there.

Between Bangkok US embassy and Chiang Mai US consulate, which one offers highest chance of a fast processing/issuing visa?

Also, is it recommended to hire some sort of agent to help making this process quicker?

(Adms please delete if it's not on the scope of the group)

Thanks!

Hey everyone,

How long does the process typically take to get your visa when you send it in to the embassy? If I overnight it on Monday the 4th, think it’s enough time if I fly Thursday the 14th? I live in NJ and applied to the NYC consulate.

Do I also need to apply for a COE?

Thanks!
