do you have any idea how to be able to work in multiple province in Thailand ?

thanks

If your job description requires you to work at different locations in the country it can be noted in the work permit when it is issued.

If working for different employers then it would get very complicated to do.

I have a 2nd company noted as employer in my WP in another province. The Labour department requirements for the 2nd company are the same as the first. However since it doesn't involve immigration, there is no income requirement. In fact I get no salary at all from the 2nd company.

I submitted the documents and original WP to the Labour department in the other province one day and picked it up the next.

I believe it is quite easy to add a second or third workplace and a second employer. A second employer needs the written consent of the first one. Many people get into trouble because they fail to do this, thinking it is either unnecessary or too hard. I know two people whose PR applications were rejected a couple of years after their applications for doing second jobs not noted in the WP.
