But for someone who does not plan to stay long in Thailand, and is in the country for specific reasons or short business engagements (like attending a seminar or meeting, or purchasing items for export) and who will not be working for a registered Thai company, need to obtain the WP.11 kind of work permit. The WP.11 is sometimes referred to as a “temporary work permit”, in actuality it has to do with the kind of work being done. The WP.11 Work Permit is issued to foreigners who are engaged in “work which is of necessity or urgent” and for a short period. This “necessary and urgent work” is broken into 6 categories and defined by the Department of Employment under the Working of Aliens Act B.E. 2551
