Can Australian expats apply for a Non-Immigrant B visa after entering Thailand on a visa exemption?

If your employer is already working on the needed documents, it is more easy to apply abroad at a Thai Embassy for the Non Immigrant B visa (less requirements).

Let your employer send all the documents to you and apply before you make your way into Thailand, no hassly about entry without visa and onward travels.

1. Yes. 1,900 baht

2. Probably but depends on the documentation from your employer.

3. Potentially. It would probably be your airline that has the hang up with no onward flight. You can get a cheap one way ticket to anywhere out of Thailand.

Whether you can or can't get in country 90 day Non-B visas issued by the immigration office in the area where you live/work will depend more on whether your employer can meet the requirements.

You certainly CAN do it from a visa exempt entry.

You are allowed to get ONE 30 day extension on a visa exempt entry for 30 more days for 1900baht at the immigration office.

You have far more chance being denied boarding when you check in to your airline flying in without a thai visa in your passport without onward travel. Many air carriers have mandatory onward travel rules if you're coming here visa exempt because if you're denied entry they have lug you back on their dime 😮

Call your air carrier and see what their policy is flying to thailand visa exempt

Also maybe have a letter from your employer stating they request you be allowed in visa exempt because they're going give you a job and get a Non-B visa for you inside the country once you're here
