After you had your degree certified etc and finally obtain your WP and visa, if in the event you need to change job and get a new wp do you need to go through the process of getting your degree certified back in the uk again?

What happens with regards to a non immigrant B visa if you wish to move jobs. Is it possible to keep the visa and just get a new work permit at a different place of work or must you get a new visa as well?

Many thanks in advance.

Changing Jobs: Work canceling WP. I need new a new NON-B to apply for a new WP.

Question: DO I have to leave the country for new NON-B or can I apply inside Thailand.

Note: My first NON-B was obtained without leaving Thailand

Additional Info:

New work kinda clueless about the process where old job had a dedicated visa officer so Im not expecting much assistance from new Job
