Non-Immigrant Type B Visa / Work Permit: Is there a link that outlines all requirements for getting a work visa once you are sponsored? I am trying to find out if there are any rules/laws about once you get the work visa, do you have to be back in Thailand within a certain period of time (i.e. 15/30 days) in order for the work visa to be valid? Curious about any other rules. Waiting on a response from my sponsor, but also trying to plan traveling so thought I would ask in here. Thank you in advance!!!
