Anyone knows if you can easily change a tourist visa to non-b with or without exiting the country? Before, it used to be 21 days. I heard now is 30 days before the end.

Do you have to pay tea money?

You can do it. Whether it's easy enough depends on how you get on with bureaucracy 

 

You will need documentation from your employer. There was no "tea money" involved when I did mine but that was at Chaing Wattana, it may be different in your local office.

 

Either way, it's something you should discuss with your employer.

OP, this post is good advice. 

Much will depend on your future

employer. 

Some points in  this thread.

Is it possible? That completely depends on your immigration offices. Many allow it, but some do not.

 

If you office does allow it, then it's up to your employer.  It requires a literal mountain of paperwork to convert to non-B visa inside of Thailand.  Many employers are simply not able to produce the required documentation to do it, and of those who can, many refuse to do so because if how much work it would require.  Much easier for them to have you go to a neighboring country and apply for a non-B at the Thai embassy there, with relatively little paperwork required.

Procedure for applying at Immigration is listed at No.1 here;

Often times it comes down to whether your employer can meet the more stringent requirements at the immigration office to get the 90 day Non-B issued inside the country 

Believe it or not many employers cannot 😮 and that's why they send you to a thai consulate in a nearby country to get the initial 90 day Non-B (because the requirements are not as tough at thai consulates as they are inside the country at the immigration offices)

That's why people are saying it's totally dependent on your employer and their ability to meet the requirements as well as your requirement to have enough days left on your current stamp to do the in country switch <- Most immigration offices (that can issue in country Non-Imm visas) require you have a minimum of 15 days left on your current stamp (60 day visa exempt, 60 day tourist visa or a 30 day extension from either of those) however SOME offices (Chiang Mai notably) requires you have 15 BUSINESS days left on your current stamp which is about 21 calendar days 

Check with your employer AND your immigration office because those are the people who have the answers you're wanting
