Both options are possible.

Your employer needs to lease with immigration to figure out what needs to be done. Sometimes easier to leave the country, buy a non b abroad and re enter. All depends how the company is set up.

1. No. But you still need Thai Pass

2. Nobody knows. If you enter visa exempt you can extend once for 30 days.

3. Any immigration office

Michelle Zaparaniuk yes, that would be the easy option of course

There is no minimum time stipulated in law as to how long you need to be out of the country before you can return to Thailand. Some land borders have a local rule of 1 day ( I can't remember where now) . It all depends on your circumstances really, how long you been in Thailand ,how many extensions bla bla bla. Also some entry points appear to be more laid back than others. Have the 3 proof of's ready and you should be good to go.

What did it say?

This is the second report I know of now. Both initial extension issued at Phuket.

You need to find a school ( language school or muai Thai or similar) and they can help with the required paperwork.
