What should I put for the departure date on my Non-Immigrant B Visa application for teaching in Thailand?

Apply for a single entry non immigrant B visa. When you arrive and have your work permit then your single entry non immigrant B visa will be extended for the duration of your work contract. There is no need to get a multiple entry visa as teachers are exempt from doing the 90 day border bounces. If you want to leave Thailand to go overseas you can get a re-entry permit. You can obtain a single re-entry or multiple re-entry permit from your local immigration in Thailand once you have arrived. With regards to the leaving date on your arrival card, simply state 90 days from your original entry into Thailand.

I did the same. I have been here for 8 years without having to do any border bounces and l came in on a single entry non immigrant B visa.

Okay, let's get to the bottom of this Non-Immigrant Type B visas are sold at thai consulates two ways

A 90 day single entry Non-B that lets you enter the country ONCE, get stamped in for 90 days and then you apply for an extension inside the country at the immigration office in your area for a year extension based on employment

OR

A year-long, multi-entry Non-B that let's you enter the country as many times as you want during the year the visa is valid for and every entry will get you stamped in for 90 days. <- People on this visa do what's called "border bouncing"; they get a 90 day stamp when they enter, when it runs down they go to the border, stamp out of thailand, stamp in and out of another country and stamp back in to thailand to get a NEW 90 day entry stamp. IF they do that every 90 days for the validity of the visa they can get 15 months of stay out of a visa that is valid for a year

NOW it is totally up to the consulate you're applying at whether they will issue a Non-B as a 90 day single or a year long multiple entry for the job you are going to be employed for.

@Ster****

, I know people who teach here for government schools on year-long, multi-entry Non-B visas where they bounce every 90 days rather than get yearly extensions from the immigration office.

for a non b you will have to leave every 90 days .
