Yesterday I tried to get answers of the next questions on the [attaya criminal:

I'm arrested in a (fake) criminal case and free on bail. The court told me that I can get a free visa from immigration during the case. But the immigration want to charge me anyway including 2000 Baht fine for not reporting 90 days. I was not able to do that because my pasport was not in my possession (now I have it back). What are the excacty rules about this matter? Can I have also a multi entry visa because I have to go working for paying my lawyers? Or can I work in Thailand?

But there was no time enough so no answer, somebody knows?

I believe you don't have to pay for not reporting, if you report as soon as possible when you are set free.

During the case against you, you can get extension of stay for 90 days at a time. These cost 1,900 a time and require documents proving that you are involved in court procedings.

Not sure if you are allowed the country, that is for teh judge to decide. But the fact that you have your passport would indicate so. If you leave the country, you will need to apply for a visa to re-enter the country.

In Thailand you can only work if you have a work permit, which only allows tyou to work for the in the work eprmit mentioned employer. So you would have to find a job first and then apply for a work permit, which would also require a non-immigrant visa.
