How can I extend my stay in Thailand after quitting my job with a Non-Migrant B visa?

@Camille ******

exactly. You are working illegally. The stay permit remains valid, but if you get caught working without a work permit, you will get arrested, court fined, deported and blacklisted.

you are NOT ALLOWED to start working, unless you have been issued a work permit by the Labour Department. If you think you can work on a job contract from your employer, you are terribly wrong and you are acting illegally

a job contract is not a work permit. A work permit can only get issued by the Thai Labour Department, and not by your employer

@Camille ******

so you said you have a "job contract" but no work permit? But you have already worked on that job? You should be aware that this is illegal. Don't tell anybody. You should NEVER have started on that job without a work permit from the Labour Department

@Camille ******

you got STAMPED "admitted until March 16" and this stamp is your stay permit, the one you received when you entered on a 90-days Non-B visa. The visa is already expired and void, you are inside Thailand on a stay permit

@Camille ******

this is complete bullshit - there is NOTHING such as a trial time without an official work permit! You are being lied to by your employer. You are getting scammed, and you are at HIGH risk getting arrested, fined, put into the detention center and deported on your own expenses and blacklisted from returning to Thailand. Stop being so utterly naive!

@Camille ******

then you can stay until March 15th. If you have an activity on March 16th, you could apply for an extension of stay without the required documentation. They'll deny the extension, but you'll get 7 days of leniency.

Do it on the last possible day, which in your case is March 14th. You'll get 7 days starting that day, so then March 20th will be your last. So it takes you only 5 days over the 15th, but if you're helped out with exactly that, just go for it.

@Camille ******

if you don't exit Thailand, you will be on overstay from the moment your stay permit expires. And it will expire the very moment you cancel the work permit. You cannot extend your stay inside Thailand - if you apply for an extension on Immigration, you will have to pay 1900.- THB and they will stamp your passport "application denied, you have 7 days to leave the kingdom". If you get arrested on overstay, you will be brought to the airport Detention Center and be forced to buy a one-way ticket back to your home country. Which way you do, is up to you, but the BEST way is, avoid to waste 1900 THB for the 7 days grace period and just exit and re-enter visa-exempt

@Camille ******

yes, you can stay until March 16th, as you said you are still within the 90 days from a single entry Non-Imm-B visa

@Camille ******

okay, if you are still on a 90-days Non-Immigrant-B visa, your stay permit will remain March 16th.
