Changing 90-day Non-B sponsors

[OliveZM]

Does anyone know if the original sponsor of your initial 90-day non-B must be the same company that provides you all the documents for the Work Permit and subsequent 1-year non-B extension?

 

For example; company A helped me get an initial 90-day non-B stamp. But now that I am in Thailand with the stamp, I want to be employed by company B (company A is fine with that). I have yet to begin the work permit process.

 

Does it matter to either the labor department who does the work permit, or to Immgration who gives the 1-year extension that company A and B are different? Do they even check or know who sponsored my initial 90-day business visa stamp? - (since the details are not visible in your passport)

Sometimes an embassy or consulate will hand write the name of the sponsor on the bottom of your visa vignette in ink.
